Btw, if you already have Magisk and Magisk Manager installed, and you want to update to the particular Magisk version (not the latest offered by Magisk Manager), you can:

- Open Magisk Manager, Modules, press on + (Plus) sign

- Navigate to your local Magisk.zip copy for that particular version

- It will do the Direct update to the particular version you gave it the downloaded zip file

E.g., you have Magisk v18.1, now the latest offered by Magisk Manager is v19.1 (even if you choose Update channel: Beta), but for some reason you want to update to the previous Magisk v19.0 Beta zip which installation file you have found and downloaded from Internet :)

Hello everyone. I tried to rteset my phone in order to debrand to nougat but now phone stuck after a simple reset and now my pc cant even recognize it..
[Huawei P9 Guides, News, & Discussion] zgfg:
Two methods for going back from Oreo to Nougat and debranding from AL10c00 to L09c432 or so are described in the OP post #3:

https://xdaforums.com/showpost.php?p=77161314&postcount=3

They don't start with Factory Resetting. Actually, it's been mentioned here many times to be very careful with Factory Resetting - it must not be triggered with Root and/or TWRP because you may brick your phone - seems you just did that

Try to restore AL10c00b540 with eRecovery method (its been described several times here, you may Search for eRecovery and/or find it in the OP posts)

Hi all, my old issue that Google Messages did not stick default messaging app solved (most likely by a scheduled update of Messages) or I dont know how.

2) I could configure a SIP account by using Quick Shortcut Maker, but it does not accept calls yet. The Settings in Phone Account Settings is missing the SIP Settings part at bottom. I am not so good with this TWRP but in this thread at sony someone managed to get the menu activated. check the post from ‎2018-08-06 07:02 PM, in this thread.

https://talk.sonymobile.com/t5/Xper...issing-build-32-2-A-0-224/td-p/1131876/page/5

maybe someone knows how to adapt this hack for our AL10?

3)

yesterday i made a successful sip call already, still often it asks for a sim card if connected via wifi, i dont know why, so most trys the sip showd at the point after chosing call in google phone app, that i should chose a sim card for the sip call (at wifi usage?) hmmm

thank you
[Huawei P9 Guides, News, & Discussion] zgfg:
You say you made a SIP call - Do you have a public SIP account like Sipnet, some proprietary VoIP account as part of e.g. communication in your company or you mean a SIP account as settings for the VoWiFi/VoLTE with your mobile provider?

Are your SIP settings integrated to the native System/Account settings and you make/receive calls by using stock dialer?

The link you have mentioned and the post you are referring (45/45 ?), looks like a proprietary SIP/VoIP for Xperia.

Did you find the some similar files under OEM on AL10c00 to make it work or how?

With the Quick Shortcut Maker you have assigned VoIP calling with some contacts, or with calling activity?

You say it's asking for SIM when connected to WiFi - looks like it should be really part of the VoWiFi/VoLTE service with your provider?

Do you have SIM card in the phone....
[Huawei P9 Guides, News, & Discussion] ant0nwax:
i use cheapvoip and sipgate as voip providers since decades ;) never really working in the native android settings, the sony phone has the settings disabled like the huawei phone because people shall talk with gsm providers and not over the top with voip on data services, maybe easier tracking and reporting ;) also income for providers... i can imagine why this topic is still not very well known, but it existed in android 4 already.

here you see some screenshots, if sth is not clear i answer tomorrow, in Singapore it is night now ;)
[Huawei P9 Guides, News, & Discussion] zgfg:
Yeah, SipGate, I'm little rusty, it's been years.

SiP standard VoIP services never gained critical mass (they were relatively complicated to install/configure and came even before smartphones).

Later, proprietary solutions (based on messaging), WA, Skype, etc became popular, and nowadays are used for free calls over Internet.

Although, SIP is now built into VoLTE and IMS.

Nevertheless, how did you unleash (hidden) menus:

- Internet calling SIP account

- Call account settings

- Calling accounts

I'm curious, I could see if i still have some SIP accounts (or could register again).

Maybe, that makes a holly grail to enable VoLTE.
[Huawei P9 Guides, News, & Discussion] zgfg:
EDIT: Ok, I got the menus :)

Registered for sip.linphone.org account

Can make call to sip:thetestcall@sip.llinphone.org

by linphone app

but cannot make dialer to call a Contact with Internet call field

sip:thetestcall@sip.linphone.org
[Huawei P9 Guides, News, & Discussion] ant0nwax:
Great to hear that you succeeded.

You know I was rebranding my phone on a long journey and tried this setup in the following countries:

Singapore: working with both simcards, but 2G bands are really rare.

Australia, Japan, Korea (South): just one simcard, no 2G in that country anymore.

cant wait to get back to Europe for full experience

so in Australia my phone hit the ground, display broken, here in singapore they changed display incl new original windowed case and screen protector and one hour work for all together 68 eur ;)

now i have a new screen just the original screen was more bright and colourful.

i say better a readable pale screen than a original broken one.

i installed google phone and messages (from android shop) and got them integrated. also i run nova launcher, phone rooted magisk 19.1 and mgr 7.1.2, safety check trustworthy, google pay installed.

1)

i wonder how can i try/test if google pay is working? i am curious

2)

i forgot how to check for updates, new security patch is available maybe?

i think i need to reflash stock boot, just i read many people brick their phone, is the magisk to be removed before? where are the steps described for this setup to go back to mode where in about phone can be checked for updates?

3)

good luck for playing with SIP

i will continue to play with that too

do we have a working twrp with local storage meanwhile?

kind regards from asia.

Instructions thanks to [MENTION=808575]ant0nwax[/MENTION] and his hints in the post:

https://xdaforums.com/showpost.php?p=79544409&postcount=1743

- Sign for a VoIP service. I used iptel.org, they provide free VoIP accounts:

https://www.iptel.org/

- Install Quick Shortcut Maker from Playstore, open and go to Apps tab, find Phone, click on, scroll down and click on SIP settings activity

- Edit: There is a better app (similar to Quick Shortcut Maker but with more options) Package Manager, also from Playstore

https://play.google.com/store/apps/details?id=sarangal.packagemanager

- Click on Try, (Launch in Package Manager) it will open hidden SIP account menu, click on Add account and enter your SIP settings for your VoIP account

- For iptel.org VoIP account, use SIP settings as on screenshot (put your registered username and password)

- Now, you can uninstall Quick shortcut maker

- Reboot (not sure was it necessary)

- Go to Settings, Wireless and network, Call settings, enable WiFi calling, and scroll to the bottom, you will find this new Phone account settings, open, here you have your previously entered SIP account

- Enable calls over that SIP account, for me Ask first (on call) did not work

- Open Contacts, add a new contact, Add additional field, choose Internet call and enter the SIP URL. On screenshot, I used echo@iptel.org (call and listen to yourself what you speak)

- Make a call to that contact, I had disabled SIM to make sure it was calling over WiFI (see No service on the sceeenshot)

I have no VoLTE service with my SIM but maybe one could enter his SIP credentials for his VoLTE IMS account, maybe it will enable VoLTE (?)
[Huawei P9 Guides, News, & Discussion] ant0nwax:
Hi folks, hi zgfg,

thanks for documenting this in a better format

corrections in your text:

SIP activity = SIP Settings

enable VoIP Calls = Wi-Fi Calling

your screenshots show correct text

questions:

1)

in enable Wi-Fi Calling submenu, what did you setup there?

2)

i can only make one call after reboot

afterwards, it asks me often which SIM i would like to use, check my screenshots in the post with many screenshots. sometimes i can solve it by setting flightmode and back to no flightmode, sometimes reboot. so it is intermittent.

EDIT: ok this seams to work if you add the phone number in format +1234567890@sip.provider.tld to SIP/Internet call (depending which category is available. in Google Phone it is called SIP, in Huawei Dialer it is Internet call)

3)

did you find the SIP Settings portion of the Phone account settings menu, where you can setup the accept incoming calls? this was my initial question, i cannot get this so in Quick Shortcut Maker Try Sip Settings (different menu than in the sony post) and different menu from phone account settings, it writes not receiving calls, check my screenshots.

we could setup a voice talk on skype if you are more curious. i am ant0nwax there too. just usually not logged in.

goodie for germany:

register your free incoming phone number at sipgate.de, you need german address, most likely checked via schufa check. then you use sipgate for incoming and iptel (or cheapvoip) for outgoing calls.

i have this setup since 20 years and never paid to sipgate ;) big thanks btw to sipgate ;)

i use it at home on my fritzbox in hungary and i used it on gigaset ip phones before in hungary and germany. Attention: some ISPs use 5060 udp for their own ip phone services, so set your connection midem/router to switch/through mode and get a real router behind, like a fritzbox or anything else. I have a mikrotik in between modem and fritzbox and the mikrotik has a LTE uplink too, if modem or electricity dies. then ups serves mikrotik and fritzbox and internet is from lte.

ok that was very offtopic, sorry for that, i just wanted to share this setup.
[Huawei P9 Guides, News, & Discussion] zgfg:
Ok, corrected wording and extended with more screenshots:

1,2) For me it always calls SIP contacts over WiFi (not asking about SIM) but check:

- screenshot #7 (my previous post), I'm using WiFi preferred.

- screenshot #8, SIP account must be enabled

- screenshot #9, Make (SIP) calls with SIP account (not with SIM card).

Ask first (on call) option does not work for me (noted in my previous post), if I close this setting window and reopen, SIM card will be selected for Make calls

- screenshot #10, use Internet call field for SIP contacts (it was noted and shown in my previous post).

Btw, calling from Call log does not work for such SIP contacts, it makes SIM call, not Internet (SIP) call (?!)

3) Many years ago I had several SIP/VoIP accounts but didn't use them and lost credentials (some services don't exist anymore).

Today everybody is on WA and you can make cheap calls to PSTN over Skype.

Besides, international rates are lower, calls and roaming in EU costs like local calls.

I signed now only for one iptel account, hence I didn't test incoming calls (I assume they will ring) but tested how to make SIP to Register (login) and to Invite (outgoing calls), and tested calling to the common testing echo account.

There are only bare bones settings, many things are missing or not supported:

- Only UDP or TCP, no TLS option (some firewalls block VoIP, if encrypted by SSL they cannot detect SIP)

- Cannot configure STUN (VoIP may not work behind asymmetric NAT)

- Cannot select which codecs to negotiate (don't even know which are supported by the built in stack), it can cause problems if the other side VoIP client supports only some/specific codecs

- Etc

Sipgate) Since I lost my old accounts I tried to sign these days again but now they no more offer personal accounts, only business plans (numbers for the whole company) and they ask for German business postal address.

Similarly with Sipgate UK, thus I signed with iptel for the new VoIP account to test

PS: Once I even flashed ddwrt open source to my home Linksys router/AP and set up my home VoIP server. But two+ years ago sold that Linksys router
[Huawei P9 Guides, News, & Discussion] ant0nwax:
Thanks, I did not know this with sipgate, I wonder when sipgate will cancel my account :)

Still I used now with the setting at SIP number to call many people form Singapore to Europe and it worked great, good quality, native client finally is cool in Oreo, compared to Android 5/6 where I tested last time

And for incoming calls on my German Fixed Line number I have to launch an additional tool

and for encryption, I agree that I would like to use SRTP or ZRTP connections for SIP, just neither sipgate nor cheapvoip support those, or the codecs you are talking about, so its more a fun and game level setup than a professional one. Sound Quality is better for Skype and Signal Messenger that I use as the only messaging tools today next to email, I just stick to Cheapvoip because usually a call is 0.01 cent / minute … how much does skype cost for fixed line calling... I set up Google Voice and used 10$, the result is its MUCH more expensive than cheapvoip. One advantage was I could call service numbers, so it can replace fixed line. Cheapvoip cannot replace a real phone because you cannot call service numbers. Can Skype do this?
[Huawei P9 Guides, News, & Discussion] zgfg:
SRTP/SRTCTP means Secure (encryption and authentication) Real Time (Connection) Protocol, it secures RTP=Media (codecs), since RTP usually goes over UDP (if some packets get lost, they don't need later resending what TCP assures because the real time talk has already gone further).

So SIP should better go over TLS (TCP over SSL) for encryption and authentication, than over pure TCP (or even worse, pure UDP)

With Skype, you can make calls to everywhere, incl. to local 800 service numbers (I think you don't even pay for 800 calls), because Skype has local trunking centers to PSTN (eg, even per every big city in US).

However, Skype to PSTN is blocked in India

Used NetCapture application to capture SIP Invite negotiation from the Phone dialer (VoIP call to echo@iptel.org)

In Session Definition Protocol, it offers the following (audio) codecs:

a=rtpmap:96 GSM-EFR/8000

a=rtpmap:97 AMR/8000

a=rtpmap:3 GSM/8000

a=rtpmap:0 PCMU/8000

a=rtpmap:8 PCMA/8000

a=rtpmap:127 telephone-event/8000

a=fmtp:127 0-15

That is, supported codecs are:

GSM and GSM Enhanced Frame Rate

Adaptive Multi Rate Narrow Band

G-711 U and A Laws

and

DTMF out-of-band signalisation for telephony events 0-15

Also, it uses RFC 3581: rport extension (standard in IMS), which is a SIP built-in replacement for STUN, to make SIP working over Network Address Teanslations:

It's possible to make TWRP reading/writing Data partition and Internal memory.

With this, you can e.g.:

- Make full Nandroid backup (including backup of Data partition) saved to Internal memory

- Wipe Dalwik cache from TWRP (Dalwik is actually a folder on Data, without this hack TWRP could not access and wipe Dalwik although it did not report an error)
