SRST not Test OK

[spverizonrd]

My scenario:

We have a CCM cluster on city A and a router 2811 on city B, the call processing is OK, but the SRST Test not.

When We apply ( disconnect ) fail over to simulate SRST mode:

1.- Call over T1 go 120 IPM

2.- The POE switch send traffic over wan

3.- The call Manager not certify the secure SRST, retur error

Thank,

Please post your SRST router config.

Juan,

Your Secure SRST config is not complete. I would suggest you to get regular SRST working properly prior to configuring Secure SRST. (One step at a time).

Sir,

Can you refresh me the step?

So I need to run a check list to verify

Thank

Juan

To add Secure SRST into this picture, you need a CA server (can configure your SRST router to be the SA) For this you need Advanced IP services or better feature set to support both voice and encryption. Here is a good link to start with for Secure SRST.
