I have a VG200 running MGCP that is connected to a PBX thru a T1 trunk. Calls can be placed and received correctly. However, when calls are placed from outside the PBX to an IP Phone thru the VG200, the caller does not hear the phone ring. We do not get ringback (and I would also say no progess indicators, such as busy signals are heard either). When the user on the other end picks up, the conversation functions fine. The VG200 is configured with an NM-HDV and a VWIC-1MFT-T1, and is running 12.2.15.T. CallManager is running 3.22c with all the latest patches. The T1 trunk is configured as E&M wink start using all 24 channels. What am I missing?
Go ahead and post your config and I will take a look at it. I assume that you already have 'voice rtp send-recv' in your config. Also, you might take a look at the following info on CCO if you haven't already done so...
Thanks much for your input. The document you refered to is more related to H323 than MGCP. I did try the various voice commands in the document but they did not solve the problem. Since I am using MGCP I cannot add the progress indicators to the dial-peers. Anyway, I have enclosed a copy of the config to look at.

Which specific 3.2.2 service pack are you running?
The progress_ind commands will not apply since this is MGCP. There's the concept of MGCP events and signals that are involved here. To get a closer look of the problem, capture the output of debug mgcp packets when recreating the problem.
We are running 3.22c with SP-F, and Win2k SP3-SPI. If I debug VPM and VTSP I can see ring tone passed to the PBX, so it would appear that the PBX is not passing the ring tone to the PSTN, although he passes it to PBX callers (internal calls).
have you checked the network locals for the gateway? i had identical symptoms with a ws-x6608, were the correct locales hadn't been installed. this can be easily verified by checking the tftp server logs for errors.
Locales are set for United States. If I debug VPM and VTSP I can see that the VG200 is passing ring tone to the PBX trunk link. At this point it would appear that the PBX is not passing the ring tone to the PSTN (he does pass it to PBX callers). I will be working with Avaya on the PBX tomorrow. Hopefully we can come up with something.
I can not rember for sure since it haas been a while since I was on 3.2 but I did have a vg200 connected to a avaya pbx. under the gateway configuration on the callmanger there is a check box that says some thing like Setup non-ISDN Progress Indicator IE Enable check this box.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
