Hello,
I have a router Cisco 2821 with EVM module 8 FXS + 4 BRI and GSM Gatewat Ecotel Vierling GSM3-1F which has a FXO and FXS ports.
I'm controlling the router interfaces by mgcp and tried to connect the GSM Gateway. The problem is that the GSM Gateway expects the digits after it goes off-hook but the CCM sends them before that.
I want to develop a method to send the digits inband.
Now it works with access code 8 and then users dial the phone when they head the second dial tone but it is not very convenient.
Further thank for any ideas.
Best Regards,
Zdravkov

This link doesn't help a lot. But fortunally I have solved the problem. I make change in the design:
Phone -> CCM -> H323 Rotuer ->FXS ->GSM GW
Now it works.
