SRST config correct?

Hi,

can somebody prove my SRST-config?

I configured an mgcp Gateway and connected to Callmanager 7.1.5, all working fine. In SRST-Mode Calls come in over teh bri0/0/0, but the call isn't connected to the connected Extension.

And teh other way, outbound: The IPC calls out, in "deb isdn q931" i've seen the correct dialed number. The same config at another Gaetway works. I tested IOS 12.4(15), 15.0(3) and 15.1(4). the same Issue.

"sh isdn status" is ok.

devoip01#sh isdn status

Global ISDN Switchtype = basic-qsig

ISDN BRI0/0/0 interface

        dsl 0, interface ISDN Switchtype = basic-qsig

         **** Slave side configuration ****

    Layer 1 Status:

        ACTIVE

    Layer 2 Status:

        TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED

    Layer 3 Status:

        0 Active Layer 3 Call(s)

    Active dsl 0 CCBs = 0

    The Free Channel Mask:  0x80000003

thx

Ronny

Hello,

As far as i know , MGCP can't work with SRST , however it maybe , i never seen it before , when MGCP gateway fall into the fallback mode , the default H.323 application works , check the below URL , it will help you with the config for this :

Hi Ronny,

Remove command "service mgcpapp" command from the dial-peer. We dont need that command from 12.3(7)T and later.

If above does not work please capture debug isdn q931 for outbound/incoming call.   Also sh ccm-manager output in srst mode.

Thanks
