dial-peer matching/best practice

Hi

we have a call manager cluster with a H323 gateway, DID range is 200X, telco sending 4 digits to the PRI

we also have a non-DID range, 201X

on the h323 gateway, we have below dial-peer configured

dial-peer voice 2000 voip

destination-pattern 200.

session target IPv4:CM_IP

codec

blah

dial-peer voice 1000 pots

incoming called .

direct-inward-dial

port 0/0:23

dial-peer voice 100 pots

destination-pattern 9.T

port 0/0:23

when PSTN caller called one of the DID, 2001, the incoming dial-peer is 1000, and outgoing dial-peer is 2000, this is clear

when one of the DID making PSTN call, I would guess the incoming dial-peer is 2000, and outgoing dial-peer is 100

how about the non-DID making PSTN call? which incoming dial-peer would be matched? default dial-peer 0? what is the dial-peer 0 default config?

if matching the default dial-peer 0, as best practice, do we need add a specific dial-peer like

dial-peer voice 50 voip

incoming called .

thanks

Re: dial-peer matching/best practice

Hi

I would concur with your first two statements.

For the final one, the call would match peer 0, and get default settings. This process (and peer 0) are described here:

You can do a debug voip dialpeer to see what is being matched.

You could fix this lots of ways:

1) Adjust the destination-pattern on peer 2000 to be 20[01]. - yes, calls should never get routed out via it, but it is used as a match for inbounds calls

2) Add incomining called-number . to the 2000 peer, so all VoIP calls hit that.

3) Add another dial peer same as 2000, but with 201. matched and same settings.

Re: dial-peer matching/best practice

Thanks Aaron for your reply.

for the non-DID, here is my opinion regarding your reply

add destination-pattern would not make sense, because it confused with DID range

add incoming called . to 2000 dialpeer would case confusion as well for troubleshooting

I prefer the 3rd option to have a separate dial-peer with incoming called . only, not destination-pattern

what is your opinion?

thanks

Re: dial-peer matching/best practice

Hi

As I say, all should work, so it's whatever you are most comfortable with.

I like option 3 as well. Just proves that the first thing you think of isn't always the most sensible :-)
