I was trying to use an iLBC codec to make a call between 2 Quadros with firmware version 4.1.18FX.

I have made a route, and configured UES for a virtual extension(60) only with iLBC enabled. But for my surprise, I get a busy tone.

If I enable G.729a codec, the call is established normally. But, in SDP of INVITE packet, I can only see the G.729, despite the fact that iLBC is also enable.

Bellow is "Call Controlling" Log, with iLBC only:

Well, as it could be concluded from the foloowing line: "no intersection with codecs of UE 60, excluding record <1???>.", the extension 31 also has to have the iLBC codec in its codec list.


Actually this behavior is new in 4.1. Before (in 4.0 and earlier) Quadro ignored the codecs of the calling extension, when making a call through a rule with UES set.
I agree, we would need to document this better...
