[Asterisk-Users] Diax IAX2

[Michael Welter]

I've downloaded diax-0.9.6b and configured for IAX2.  Calls from Diax to 
  * are perfect.  However, when calling from * to Diax, I get the following:

  channel.c:1097 ast_read: Dropping incompatible voice frame on 
IAX2[mike]/3 of format GSM since our native format has changed to ULAW

In iax.conf I have:
allow=all
disallow=g723.1
disallow=lpc10
allow gsm

Has anyone else seen this?

Thanks,
Mike
