SRST Fallback trouble with FXO port
|
|
| DUNCAN, W B. 2007-04-23, 7:11 pm |
| I have been setting up a new series of dial-peers for our remote sites
(on our test network) to better resemble normal dialing when they go
into SRST fallback. I have most everything working, but with the
current config in SRST mode, when the FXO line is dialed, the router
gives a dial tone. You can then dial one of the extensions on the
network, but I want it to automatically forward to the
default-destination I have configured in call-manager-fallback. I am
sure I am just missing something, but I sure don't see it. Does anyone
else have an idea why this is not working for me?
Thanks for the look,

| This is known as two-stage dialing vs one-stage dialing. It through me off to begin with. For PRIs I simply added "incoming called-number ." and "direct-inward-dial" to at least one dial peer that had that port as the member and it worked. However, I don't think FXO ports support this solution and likely require a "connection plar <dn>" config line. Take a look at the following doc, it should help:
