Hello guys!
Currently I'm configuring SRST on a Cisco 2921 in conjunction with a CUCM8.6 (BE6000). When testing SRST, the phones show "MODE SRST", some pick up dial tone, some not, and on phones with dialtone phone calls did not progress. On the Cisco 2921 the debug ccapi all did not show nothing when attempting calls during the SRST test. It appears to me like phones were unable to register with the Voice Gateway (Cisco 2921). Below is the partial SRST config of Voice Gateway. My questions are the following:
1. Does it is neccesary to configure manually the ephones and directory numbers in the Cisco 2921 or phones will be allocated by the router automatically?
2. How to determine the SRST versipon currently running on Cisco 2921? Phones are 7940, 7960 and 7912.
3. On dialpeers (both voip and pots) it is necesary to enable the service mgcpapp in order to permit SRST calls to flow through the dialpeer?
4. Please reviw the SRST config below and if I'm missing something let me know!
Thanks in advanced guys, appreciate your help.

Hello guys!
When placing outbound calls, the digit 9 is not being stripped from the dial string, hence the call gets disconnected. See debug output below:
Calling Number=7875239999(TON=Unknown, NPI=Unknown, Screening=Not Screened, Presentation=Allowed),

Te dialpeer matched is:

I also tried with 9T, but same result. Any ideas on how to remove the digit 9 from dest=97872350808?
Thanks in advanced guys!

Thanks for all your help! SRST is working as intended. Outbound calls were failing due to invalid country codes configured on the voice-port. I removed those from the port and is working now. Thanks again!
