Hello!
For fallback from MGCP u need:
application
global
service alternate default
You alrady have it
Do u have any problems with SCCP endpoints? Calls from SCCP to SIP?
Please, post 'debug ccsip messages' while trying to call.
Regards,
Kirill

Hi Kirill,
Thanks for your reply. As I mentioned earlier, I was getting error while configuring commands for MGCP fallback.
Actually I had executed commands in SRST mode when Gateway was not registered with CUCM ie MGCP was down, hence it was giving error for "Application.... global .. commands".
I reconfigured same configuration keeping gateway registered with cucm & reloaded the router. Post this, tested SRST n extension to extension calling starts working.
Thanks for your valuable time.
