Possibly or possibly not. Most (IMO) calls are placed initially with the choice 2-3 or more codecs. Normally one codec is negotiated and life goes on, but IAX is a little different from a SIP/DAHDI call. The most certain remedy I can think of for this it to just "unallow" the alaw codec on IAX calls.

[Apr 29 14:46:30] NOTICE[32175] channel.c: Dropping incompatible voice frame on IAX2/trunk1-9085 of format alaw since our native format has changed to 0x4 (ulaw) If voice frames have been dropped then I suppose that the call quality may be affected?
