I currently have a 3640 w/ 12.2(11)T that is acting as a remote site SRST gateway. It is talking to a central 3.2 Call Manager. I configured the 3640 to be a MGCP gateway, with SRST and MGCP Fallback.
I am running into an issue w/ the FXS interface on the 3640. I have an analog phone connected that is able to place and receive calls while the 3640 is running in MGCP mode. When the WAN fails and H.323/SRST kicks in, the phone can still receive calls but is unable to place them. It gets a fast busy signal.
Here is the 3640 config:
