I have a 3 site cluster
site A has pub and sub1
site B sub2
site C sub3
All PSTN calls arrive at site A.
On the gateway for site A.
Should my dial-peer point to the Sub1 at site A. as the PUB is not doing call-processing?
or would it be better to point the site specific range at the relevant subscriber?

Yes, this is correct, any subscriber, as well as the publisher, can handle call processing.
Hope that helped, if so please rate.

Hello,
Just configure your dial-peers using the "preference" statement, and point each of them to a subscriber, and point the one with the lowest preference to the pub. This way, if any of the subs are down, calls can still be processed by another subscriber. See example:
dial-peer voice 1 voip
destination-pattern .T
session target ipv4: [sub1 IP]
dtmf-relay h245-alphanumeric
dial-peer voice 2 voip
destination-pattern .T
session target ipv4: [sub2 IP]
preference 1
dtmf-relay h245-alphanumeric
dial-peer voice 3 voip
destination-pattern .T
session target ipv4: [sub3 IP]
preference 2
dtmf-relay h245-alphanumeric
dial-peer voice 4 voip
destination-pattern .T
session target ipv4: [Pub IP]
preference 3
dtmf-relay h245-alphanumeric
Hope that helped, if so please rate.

many thanks,
so if for example a PSTN call comes in on the gateway at site A and it is destined for a DDI at site C, any subscriber can do the call setup. It doesn't have to be done by sub3 at site C.
