[Asterisk-Users] Need help to format asterisk MGCP packet.

[Duane Cox]

YES, that change in the chan_mgcp.c worked for my setup.  Like I said before, it may not be the best long term solution.

What would need to be done to get this into the CVS?  Maybe not this exact hack, but some sort of option to allow the change in the format of the packet?

ODDLY, the device sends up to asterisk in that format, and asterisk could understand the device, it just couldn't communicate back (before the change).... 

Apparently with this STACK used by this device, the manufactuer is dead set on NOT changing it. I am finding that there is no 'true MGCP standard' as I work with it between vendors....
