H323 Redundant Call Path

Hi;

I am over looking something fundamental in regard to creating a redundant dial-peer. I have 2 H323 PRI gateways that are working fine. However I need to be abe to route calls between them if the H323 path in the other fails. This is needed to prevent calls from failing as I have one DID range over the 4 PRI circuits with calls being delivered cyclically across them.

I created a H323 peer on both routers and the call passes from one to the other (this is where it starts to go wrong). When the call is received it matches the new incoming H323 peer on the DNIS 12[3-4]. (test range i have). I would then expect it to match the outbound H323 peer as that peer has a destination-pattern of 12[3-4].

But instead it matches the outbound PRI peer that has an incoming called-number of . and a destination-pattern of .T

Can anyone clarify why this is???

The peers in question are below:

dial-peer voice 301 voip

description incoming from site A

no modem passthrough

incoming called-number 12[3-4].

voice-class h323 1

dtmf-relay rtp-nte h245-alphanumeric

codec g711ulaw

fax-relay ecm disable

fax rate disable

fax protocol none

icpif 10

expect-factor 5

no vad

dial-peer voice 100 voip

description MG to SBC (non cisco)

destination-pattern 12[3-4].

progress_ind setup enable 3

no modem passthrough

session target ipv4:10.10.10.2

voice-class h323 1

dtmf-relay rtp-nte h245-alphanumeric

codec g711ulaw

fax-relay ecm disable

fax protocol none

icpif 10

expect-factor 5

no vad

dial-peer voice 5 pots

description PRI Out

translation-profile outgoing PSTN

destination-pattern .T

incoming caled-number .

fax rate disable

no digit-strip

direct-inward-dial

port 0/0/0:15

forward-digits all

Thanks for all and any suggestions in advance

Tim,

So that looks like dial peeer 100 became the best INBOUND match.

How about trying some digit maipulation.

!

!

voice translation-rule 301

rule 1 /^12/ /5555/

!

voice translation-rule 100

rule 1 /^5555/ /12/

!

voice translation-profile 100TEST

translate called 100

!

voice translation-profile 301TEST

translate called 301

!

!

!

dial-peer voice 301 voip

incoming called-number 12[3-4].

translation-profile incoming 301TEST

!

!

!

dial-peer voice 100 voip

incoming called-number .

destination-pattern 5555

translation-profile outgoing 100TEST

!

!

You will need to try with your preferred DNs - I just suggested translation numbers starting 12.... to 5555... then back again.
