Have a MGCP site with two FXO ports for connection out to the PSTN. I keep dropping calls, the VoIP phone shows "temp fail" when it drops and I'm having trouble deciphering the debugs. I think there is a timer somewhere in the config just not sure where to look. See attachments for show run / ccapi debugs / mgcp debug. ccapi and mgcp debugs are from two different calls but on the same port and were placed one after the other. Also I cut the MGCP debug to right before the disconnect.
Originally the drops were happening at intermittent times, I added a few lines tonight and I had 3 straight calls last for 12 minutes before dropping.
lines added:
(config-gateway)# no timer receive-rtp 1200
(config-gateway)# no media-inactivity-criteria all
and
"no vad" to the voice ports last night
Any help is much appreciated.

Hi,
I think you need to look at your MGCP config on the router.
You have
mgcp bind control source-interface FastEthernet0/0
mgcp bind media source-interface FastEthernet0/0
However int f0/0 is shut.
The config you have shown is incomplete but
I think your voip is using VLAN 200 on the 10.200.60.0/24 subnet
Try reconfiguring the mgcp
!
mgcp bind control source-interface vlan 200
mgcp bind media source-interface vlan 200
!
exit
!
wr mem
!
conf t
!
no mgcp
mgcp
!
exit
Regards,
Alex.

Oiy, yes that would help. I'll give it a try and report back in a day or two. Thanks.

Had a co-worker apply this change today, then placed a test call, it dropped at about the 4 minute mark. This site is running back on a VPN connection thru a SonicWall...if that helps.
