| If I have 4 FXO ports on a 2801 running 12.3(14)T5 that goes into SRST
(MGCP VGW) which port will it start dialing out on then which is next
etc.
Reason I ask is this VGW is in to different Telco areas. And the worst
part is that calls from one telco to the other are long distance. So I
don't want to get into an issue of dialing a number in SRST and the
operator saying you don't have to dial 1 then try again for it to say
you must dial 1. You get the basic idea. I really don't want to try
and setup ~150 dial peers to fix the issue. Is the easiest fix to just
remove any desination-patterns off the two ports that go to one telco?
Any thoughts?

| If I am reading your question correctly you could do something like
this:
For 10 digit local dialing you can use this dial peer to use the local
provider FXO port, assuming it is 1/0/0
dial-peer voice 5 pots
destination-pattern 9[2-9]..[2-9]......
port 1/0/0
Then if that call fails you can have the call use the long distance
provider on port 1/0/1 by setting the preference to 1
dial-peer voice 6 pots
destination-pattern 9[2-9]..[2-9]......
preference 1
port 1/0/1
prefix 1
A preference value of 0 is the default and is the highest priority. If
more than one dial peer has the same preference then you will see some
form of round robin between the dial peers that have the same
destination pattern. Otherwise the call will be extended to the
highest priority (preference of 0) first then if the call is busy the
GW will try the ext highest priority (preference of 1). You will also
want to prefix a 1 for the outbound calls using the long distance
provider.
Or, you could simply just remove dial peer 6 and only have the local
calls use the local provider.

| Me, personally, I am too lazy to create dozens of dial-peers.
So, here's what you do.
Tie all of your outbound FXOs into a trunk-group and then refer to the
trunk-group on the outgoing dial-peers.
You can also change the hunt method on the trunk-group.
