Care to enlighten us with what MGCP device you are using?

502 says "The transaction could not be executed because the endpoint does not have sufficient resources"...

You've got to be more responsive if you want assistance with your bug.  Please respond by tomorrow if you still care about this bug.

and the phone gives busy tone
By: Mark Spencer (markster) 2004-05-20 10:11:42

This appears to be related to a configuration issue.  I notice the endpoint suggests it only speaks G.723 with 30 or 60ms chunks, and Asterisk is configured for PCMU.
By: wiking (wiking) 2004-05-20 11:25:48

hmm, well as from the device's manual, the phone is:
- Compliant to MGCP 1.0 and NCS 1.0
- Voice compression: Complies with G.723.1

i've just added my mgcp.conf. sorry for being such a lame, but could you give me a "sign" how could i fix this problem - so the phone finally gets working?
By: Mark Spencer (markster) 2004-05-22 00:03:49

You need to configure the phone to use G.711 not G.723.1 and it should probably work.
By: wiking (wiking) 2004-05-22 05:38:54

i've read through the phone's manual (http://wiking.jol.hu/text/Iph-90.pdf) and i couldn't find a way of changing it's codec. i've tried to find a way with opening the phone, but no luck...

is this means that there's no way of using this phone with asterisk?
By: Mark Spencer (markster) 2004-05-22 18:11:41

Although I've never seen a device before with this limitation, I've also reviewed the document and clearly -- and for what reason, i have no idea -- only supports G.723.1 and does not allow you to use it in G.711 mode, meaning you would only be able to have asterisk behave as a switch and could not provide any real features, since transcoding G.723.1 requires licensing patents and is *extremely* expensive even in comparision with G.729.
