CME routing

[chingkiatlee]

Hi all,

Do any have the any idea if i having the local fax machine (branch) & Fax2Email solution device (HQ) at the same time.

My client willing to route the incoming call to fax to email solution in HQ first and failover to local fax machine once the WAN link is down by using the Cisco CME solution?

HQ is using CUCM version 9.1.

Is it possible?

thank you.

You can try to use dial peer with preference. First preference use voip and point to CUCM. Second preference use pots and point to fxs port

That's right. Dial-peers can be used with preferences to set up primary and secondary routes.

You don't need to put any preference command on the dial-peers to the CUCM. By default, this is 0.

You can put a preference 1 on the pots dial peers and this should do the job.

Make sure that the huntstop channel command is not present on the dial-peers.

Thanks

Hi All,

That mean the dial-peer will jump to next preferences based on the call successfully status?

Hi Lee,

The router will first try to route to the destination mentioned on the lower preference. If that succeeds, the call gets routed.

If the call through that lower dial-peer preference fails, then the router will try to route to the destination mentioned in the higher preference dial-peer. Note that both dial-peers should have the same destination-pattern.

Example:

dial-peer voice 1 voip

destination-pattern 5...$

session target ipv4:10.x.x.x

codec g711ulaw

preference 1

no vad

dial-peer voice 2 pots

destination-pattern 5...

forward-digits all

port 0/0/0:15

preference 2

dial-peer 1 will be selected and call will be sent to 10.x.x.x. If this call fails, then, the router will send the call to 0/0/0:15.

Thanks
