[cisco-voip] SRST What am I missing

Thu Jan 19 14:59:22 EST 2006

Thats a start for outbound calls depending on what you
want to call, etc, but did you check the other things
for the inbound calls?  is 6701 assigned to a phone
and up/registered in fallback mode?

When the phones go into SRST mode, they will be
registered to router as virtual? dial-peers. Your
fallback configuration allows for 24 phones and 48
DNs. 7910, 7935 and 7940 are allowed to have 1 DN in
fallback mode. So 6701 has to be first line on a phone
if it is a 7910/7935/7940 model. In fallback , try
calling 6701 from another IP phone in fallback and see
if it rings.
