[Asterisk-Users] MGCP error dialing

Sat May 22 00:49:44 MST 2004

Phillip & group,
 I tried what you suggested and it did not work i included some more information
for you to take a look at...

i have got the MGCP working sort of for my asterisk server. My phone plugged
into the dlink gateway does not ring when i call it. My sip phone does ring
when i dial the extention. asterisk CLI shows its ringing correctly.  I am
using the dlink gateway whch has 2 ports in it. I have an extention for both
ports in my extentions.conf. Asterisk appears to reconize that a phone is in
there as it does not go to voice mail right away and it shows its dialing in
the command line interface. I tried calling aaln/1 when no phone was in there
and it went right to voice mail. I plug a phone in and it just says ringing.
Below is my conf that i have now.Is there anything I need to configure in the
Dlink gateway for this to work with asterisk? my gateway works fine and i use
it normally for calls. I might have missed something very simple but I never
tried this before so i am not sure...

Wan port to switch, Lan port no cable in it.

Any ideas? I followed wiki and any docs I can find on mgcp with the
box.Everything else works...

do i need to have something in bindaddr= for mgcp.conf? I marked that out.
