[Asterisk-Users] No compatible codecs

[Rene Kluwen]

I have an Asterisk related problem with mutualphone.
I can connect to any number with any softphone that I am using (iaxcomm,
SJPhone, and a few others).
Also I have a Grandstream BT 101. But I cannot call (via Asterisk) to
mutualphone destinations. Other destinations go fine.

A working phone call (e.g. from iaxcomm) gives the following on the console:

    -- Accepting AUTHENTICATED call from 192.168.112.99, requested format =
512, actual format = 512
    -- Called 0031651931985 at mutualphone
    -- SIP/mutualphone-6b26 is ringing
    -- SIP/mutualphone-6b26 answered IAX2/iaxrene at iaxrene/2

The BT101 gives this:

    -- Called 003165193XXXX at mutualphone
    -- SIP/mutualphone-2de1 is ringing
    -- SIP/mutualphone-2de1 answered SIP/chimit01-6013
    -- Attempting native bridge of SIP/chimit01-6013 and
SIP/mutualphone-2de1

    show translation (I figure this has anything to do with it) shows that

The first preferred Vocoder configured in the BT101 is PCMU, but changing
this to G729 (the one that mutualphone is using) won't make it work. I
changed the option back again because all other services (FWD, BRI, IAX2)
work like this and I don't want to break them.

Any suggestions about what I can change to make this work?

Cheers!
