Titolo: LCP problem in 3640 with WAP phone

Hi all,
CISCO 3640, for configuration please see below, BRI ports.
The configuration has been tested with a terminal adapter, calling an ISDN
number corresponding to the BRI port 2/0. The Terminal adapter is able to
connect to the router.
I've tried to call a router 3640 with BRI slot from a WAP phone (9600 bps
and 14400, set to ISDN).
The following debug trace appears.
First of all:
routerct004#sh debug
PPP:
  PPP protocol errors debugging is on
  PPP protocol negotiation debugging is on
ISDN:
  ISDN Q931 packets debugging is on
  ISDN Q931 packets debug DSLs. (On/Off/No DSL:1/0/-)
  DSL  0 --> 31
here is how the call debugging appears:

(
http://www.cisco.com/warp/public/112/chapter17.htm#LINK
) ....."The second
type of problem in LCP is when only outbound CONFREQs are seen on one or
both peers as in the example below. This is usually the result of what is
referred to as a speed mismatch at the lower layer. This condition can occur
in either async or ISDN DDR."
CAN ANYBODY HELP ME?

 CAN ANYBODY HELP ME?
Ask whether your GSM provider translates to analog, to V.110 or
provides both. For analog, you would need a modem card. For V.110,
Cisco might be able to deal with that, but I don't know exactly.
V.110 is digital, but a completely different framing compared to
what is usually used on the B-channel (HDLC-derived protocols). On
the Ascend Max, for instance, you need extra hardware (just like
the digital modems) to accept V.110, because the HDLC processors
could not cope with it. Maybe someone operating a Cisco NAS knows
more?
