[cisco-voip] SRST What am I missing

[Jonathan Charles]

First off, do the phones register via SRST and say "CCM Fallback" when the
WAN connection goes down?

Do a 'show ephone registered' when in fallback to see if they do register
(or check the log afterwards, you should see the devices registering.

Assuming they do register, you are going to need H.323 dial-peers to get
outbound calls:

For example:

dial-peer voice 318 pots
 destination-pattern 9T
 port 2/0

etc...

You will also need an incoming dial-peer.

Because when you are in SRST mode, MGCP is down, so you need to be in
H.323mode and need those dial-peers to route calls.
