[Asterisk-Users] dlink104S->asterisk->OH323->OpenPhone

[Eric Wieling]

4 = G.711 u-law
256 = G.729A audio

So what Asterisk is saying is that the H323 device is using G729 and the
MGCP device is using ulaw/G711.

Since Asterisk can't translate between those two codecs unless you have
a G729 license installed the call fails.

Do you specify the allowed codecs in your mgcp.conf file?

If the H323 device and the MGCP device both talk G729 I can't see why
Asterisk would need to transcode the CODEC part, but it might be an
issue because Asterisk is converting from H323 to MGCP.
