[cisco-voip] SRST What am I missing

[Erick Bergquist]

What happens in fallback with inbound calls? Dialtone,
busy signal?

When the failure happened, was the router still
registered to ccm for MGCP? If the phones go in
fallback for some reason, the router may be still be
in MGCP mode so depends on how it failed or how SRST
fallback was tested.

Is 6701 registered to this router when in fallback
mode? That phone needs to be in fallback and
registered to router. You could also do a connection
plar 6701 under voice-ports to make sure; I have seen
the default-destination not work right previously.

There are also NO dial-peers configured for outbound
calls when in fallback mode (which is H.323).
