SRST with Qsig Link

Hello,

I have configured a 2821 with 1 - E1 and 2 - BRI interfaces.

The protocol used for the E1 is Qsig, the is a connection to a siemens Hipath 4000. This connection is working fine in normal mode.

When the Gateway is working in SRST mode I can receive call from the siemens I cannot make calls. In the debuging I see that I try to establish the call but after that the call is interrupted.

Does someone have more information about a Qsig link to a siemens with SRST

Kind regards

Re: SRST with Qsig Link

Hello

Thanks for your reply

Here do you have the output for the call under srst

Here do you have the output during normal CCM

So during SRST he is using channel 31 ? and I'm getting the message originating address is non-isdn
