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

[Derek Bruce]

I don't use MGCP, but after a quick look at the code I may have a solution
for you...

in chan_mgcp.c, replace the snprintf line in init_req (line#1367 in march 1
cvs version)with:

snprintf(req->header[req->headers], sizeof(req->data) - req->len, "%s %d
%s@[%s] MGCP 1.0\r\n", verb, oseq, p->name, p->parent->name);

this should give you what you need...

brackets)

> You can see the format that it is sending out, and it is expecting to get
the same format back.  You can see that asterisk is sending to the device in
the format (without the brackets) and this gateway device responds with
'endpoint unknown'
