Hello,


For what I can see, you need to enable fallback on the router.


Assuming you have configured in CCM, the SRST reference to use local gateway, here's an example of fallback configuration:


!

call-manager-fallback

secondary-dialtone 9

transfer-system full-consult

ip source-address 172.16.27.2 port 2000

max-ephones 15

max-dn 30

transfer-pattern .....

!


Let me know if it works...
