Not using preference 1 dial-peer

I've got a 3845 on IOS 12.4(20)T3 and there are two dial-peers configured as follows.

dial-peer voice 80000 voip

description Intersite Dialing via ITS-UCM02-PP

destination-pattern 001....

progress_ind alert enable 8

progress_ind progress enable 8

progress_ind connect enable 8

modem passthrough nse codec g711ulaw

session target ipv4:10.44.5.11

dtmf-relay h245-alphanumeric

codec g711ulaw

fax protocol pass-through g711ulaw

no vad

The first points to the subscriber, the second to the publisher.

When the subscriber goes down, the gateway doesn't fail to the second dial-peer. Any ideas?

Re: Not using preference 1 dial-peer

You need to speed up the H323 failover timer.

add this

voice class h323 1

h225 timeout tcp establish 3

then add the voice class to every voip dial peer. This will speed up the time to check for the pub and failover to the sub.
