I am going to implement a Cisco2821 Gateway using BRI to PSTN in Germany. I have been told that the provider support Overlap-sending which is good because I then dont have to worrie to much how to implement the dialplan in CCM.
Am I limited to MGCP or does H323 support overlap sending using BRI. I think I am looking for the Backhaul-BRI feature here but I am not sure.
Any ideas would help.
If you are using MGCP, then overlap is done in callmanager instead of H.323 gateway. But you lose lots of feature and flexibility if you do so.
It supports both BRI and PRI.
