[cisco-voip] SRST Dial peer

[Erick Bergquist]

Also,

You may need to use translation-rules, connection plar
on FXOs, alias under fallback, etc depending on your
dial plan. Especially if  under normal conditions if
your calls route to virtual numbers (not directly to
IP Phone extension that exist in fallback). When in
fallback, the IP phones that go in fallback will have
their extensions automatically added to router during
the time of fallback for up to the max-dn settings
configured, etc per phone model. Any other numbers
will need to be handled by the means mentioned above
in H.323 to get those calls to route to a phone in
fallback.

You may also want to add 'application mgcpapp' or
'service mgcpapp' to all dial-peers with a analog pots
port under them. This is so when in MGCP-mode a
inbound call doesn't accidentally terminate on a
non-MGCP dial peer and cause problems (dead air, etc).
I have seen this happen. Also make sure you have the
ccm-manager fallback-mgcp and global 'call application
alternate default' or new global application section
with default  application specified as alternate.
Without this when MGCP fails the voice-ports on router
will not go in fallback and thus won't be available
for use by IP phones in fallback.
