[Asterisk-Users] SIP to MGCP transcoding

[Michael Van Donselaar]

I am tinkering with a D-Link DG-104S MGCP adapter and then X-Lite SIP
softphone.

The D-Link supports g711 and g729.

X-Lite supports g711 gsm and g723.1.

If I enable ulaw, then I can get them to talk to each other just fine.
Meetme works fine, to.

If I add

disallow=all
allow=gsm

to /etc/asterisk/sip.conf, then meetme still works, but the phone
attached to the DG-104S cannot hear the softphone.

Is asterisk _supposed_ to transcode MGCP <-> SIP traffic?
