Need a little help understanding iax codec ordering.... Asterisk A (v1.07) -> iax2 -> Asterisk B (cvs-head, current) If both are configured with (I've purposefully left out other statements that don't pertain to the question): Type=user disallow=all allow=ilbc,gsm Type=peer disallow=all allow=ilbc,gsm a call between the two systems as shown above fails. But if this is arranged as: Type=user disallow=all allow=ilbc allow=gsm Type=peer disallow=all allow=ilbc allow=gsm the call succeeds using ilbc. Any thoughts on why the first codec ordering method fails? Rich
