3745 MGCP Cannot call out HELP!


I have a 3745 with IOS 12.3(6) running IP PLUS. I have 2 - NM-HDV with 2 2MFT-T1 cards in each. I only have controller T1 1/0 operational at this time.

Therefore I have interface Serial 1/0:23 and Voice-Port 1/0:23

I have the dial-peer 10 voice pots

incoming called number.

destinationa pattern 9T

application mgcpapp


port 1/0:23

The L2 of the PRI is up Mutliple Frames Established.

I have all my Route Patterns tied to Route Filters.

9.@ LongDistancePT LongdistanceRF PreDot

I try to make a call to the PSTN and it drops the call immediately.

I looked at the debug ISDN q931 and saw that I was sending out the appropriate numbers and it was not sending the nine.

It was working for a short while, I tried to make some changes because when trying to see if SRST was working there was NO dial-tone. After making minor changes, it stopped working again even with CCM up.

I TFTP the working config back and still it disconnects the call immedaitely.

Should I use 12.3(7)T IP VOICE instead of the IP PLUS?

Re: 3745 MGCP Cannot call out HELP!

Could you post the whole config. I have worked with a 3745 and currently 3725 and can make calls out without any problems. So it may be a simple configuration thing.
