I have centrex phone lines connected to FXO ports at one of my remote sites. When someone calls in they hear two ringback on their phone before the IP Phone starts ringing. I need to shorten the discrepency in the ringing. I don't expect it to by syncronized but I know it can be closer. I'm running H323, using CallManager 3.3(4) and running SRST on the router. I've include the relevent part of my config.
Any help would be greatly appriciated.
