[cisco-voip] Incoming call not receiving on SRST mode

[Manoj Kalpage]

Hi All,
We have Call Manager 4.1 implementation on main office and branch
office has SRST voice gateway. When WAN up everything working normal
but WAN fails SRST site phones can make call over local BRI but they
are not receiving incoming calls. As main office cannot find SRST
phones, all incoming calls to those numbers are get forward to voice
mail. I thought AAR can be used for SRST but it seems to be not. Has
anyone come a cross this kind of situation? Any kind of information
would be greatly appreciated.

Best Regards,
Pere
