Folks,

Would someone be kind enough to share their SRST configuration with the forum.

Thanks

Chris,

I am interested in the complete configuration including dial-peers. I would appreciate if you could paste the dial peer section as well.

Thanks

[Chris Deren]

You don't need to add additional dial-peer configuration in SRST mode, you use the existing pots dial-peers to go out PSTN. When the phones register with SRST, the router automatically creates dial-peers with the phones extensions, you can view them by running "sh dial-peer voice summary".

Here are the dial-peers I use:

dial-peer voice 9 pots

description 10-Digit-Dialing

destination-pattern 9[2-9].........

direct-inward-dial

port 0/0/0:23

forward-digits 10

!

dial-peer voice 91 pots

description 11-Digit-Dialing

destination-pattern 91[2-9].........

direct-inward-dial

port 0/0/0:23

forward-digits 11

!

dial-peer voice 4700 voip

destination-pattern 470.

voice-class codec 1

session target ipv4:10.233.149.21

dtmf-relay h245-alphanumeric

Chris,

I have MGCP gateways, do you have any MGCP gateway configuration with SRST.

Thanks

[Chris Deren]

MGCP gateways use MGCP fallback, which is a different feature from SRST.

Check these out:

I am having an issue with a remote site. If my 1760 loses connection to the CCM, the phones will register with gateway and inbound and outbound works fine. My problem is that graceful failover is not working. An in process call gets dumped when connection is lost between gateway and CCM. Any thoughts?
