[Asterisk-Users] Codec "Uknown" with IAX connection

I am having some problems getting TelIax service to work with *.  Outbound
calls work just fine.   When I try an inbound call the phone rings and there
is no audio.   Upon further investigation "iax2 show channels" indicates
that the codec is "unknown"   The provider confirmed that they are set for
ulaw and so am I.  Does anyone have an idea what could be causing the codecs
to show up as "unknown"?   Why would this be only failing when I receive a
call from them?

 

Thanks in advance.

 

 

I have this in my iax.conf:

 

register => myusername:mypassword at voip.teliax.com

 

[teliax]

context=in-out

type=friend

host=voip.teliax.com

auth=md5

secret=mypassword

disallow=all

allow=ulaw

qualify=5000
