I have that problem. It initially was sporadic. Now it simply doesn't record at all.

EDIT: By the way, I've had call recording working on this same rom, differant kernel and odexed rom but not likely of consequence, with InCall Recorder. I had to switch it from mic to line or phone or whatever the setting is (there's only two settings), but test the free version thoroughly as it also worked well on my previous phone but then failed on everything as soon as (I think what caused it) the band switched. It never worked again on any band (2g 3g 4g) after the initial fail.

EDIT2: This App doesn't work on the ROM regardless. Likely the phone app is indeed engaging the line for recording, is the reason, but recording itself is not happening.

Wanam, is there something we might have frozen or deleted that is a dependency? I have Tasker Deleting, for example, these files in /system/app and /data/data (in the quote box below), despite no one else seeming to have the problem with your ROM, as outlined in this post as I have a persistent notification, stating that a process is asking for inappropriate permissions or something along those lines, shortly after the device boots but deleting these files takes care of the problem before the notification would occur.

I have to delete them at every boot or they rewrite themselves and if memory serves I beleive that they initially also disabled root unless I chose to protect it in CWM; but in that scenario it would update all the system apps (184 stock) on every boot.

I actually wouldn't mind a little help on either of these issues.

1. If there's dependancies to the call recorder if its built into the phone.apk

2. Can use some other route than choosing to either delete files on boot or having to wait for 184 plus what I added to /system to update and for example a sort of unrelated issue someone had suggested they have a locked bootloader, and I don't know if I do or not but this could be my problem. I have a download file for what is supposed to be an unlocked bootloader in the form of dd images but haven't gone that route as I haven't looked into whether I need to do this on a running ROM or from a shell at CWM and concerned about bricking the phone in either scenario.

Any insight on the above from the developer or anyone else?

Nice ROM by the way. I'll be donating soon when the wife isn't looking :p

I'll also try out turning off Tasker and try call recording, though I do have other things frozen. This will mean another reflash if it deletes my su binary.. I can't remember if it did this or not as I was also at one point toying around with using the stock kernel (It doesn't work for those wondering; it boots but the modifications such as WiFi (the only thing I looked into) don't work... and its a good kernel that comes with it so I can't complain but like to tinker when time permits.

EDIT: It seems this is not necessary any more; to remove the files on boot. I don't know why and am certain that it happened more than once as this is the only custom ROM I've flashed aside from the "Worlds First something or other Stock ROM" prior to yours; perhaps an app I froze though the list turned out to be quite shorter than I thought after looking what remained since you've removed bloatware. I also defrosted the 2 additional apps that I now reconized and call recording is still not working but it seems that it is indeed grabbing hold of the line as the aforementioned 3rd party app only creates zero byte files and asks if another recorder is operating at the same time. The *Knox files are still removed though, if this makes a difference

Still Editing: I'm downloading Omega Rom to see if swapping the phone.apk will work though we will see if its the same file in the end anyway... I was never a fan of Omega ROM way on back when I had my SGS2.
