I am trying to make use of a POTS line connected to FXO port on 2851 for 911 calls going out of the router. I understand that dial-type, signaling type is important and I have checked that to be dtmf and loopstart respectively. Here is my configuration, but it is not working. The call is not getting out through this port instead using a redundant pri to go out.
description POTS line
!loopstart and dtmf are default settings
dial-peer voice 880 pots
!translation-profile outgoing pstn
Can anyone give me some ideas what else I need to check?
