calling extention number by using SRST

[jawwalit]

Dear all:

i have the following senario:

H.Q

1.gateway 2821 with FXO

2.Call-Manager

3.Extention Number 8xxx

Remote site :

1.gateway 2821 with SRST enable

2.FXO also installed on the gateway

3.Extention Number 7XXX

i used MGCP protocol , My point is when the WAN link is failed how can i configure the two sites so that extentions call each other using the FXO ports.

Regards

You need to configure ccm-manager fallback-mgcp to H.323 on the remote branch and create dial-peers to point to the PSTN and back to HQ (simply use dialpeer with destination-pattern 7... and prefix the area code NXX digits).

have a look at this:
