[cisco-voip] SRST Dial peer

[Gary Roberton]

Hello All

Thanks for all of your comments.  We have done some more work on this and
have noticed the following.  We have a pots dial peer for outbound calls and
this works fine.

Instead of using a pots dial peer we thought that the access-code line under
call manager fallback could be usedinstead.  However, we cannot see any
difference when applied.  Our syntax is;

call-manager-fallback
  access-code pri 9.T direct-inward-dial

Has anyone else seen this? We are using SRST 3.2

Regards

Gary
