Best way to call forward to external DID (CUCM 10.5)

[billmatthews]

Our environment: PSTN T1 -> CUBE -> SIP Trunk -> CUCM 10.5

We have a DID that we've moved to a hosted fax solution.  We will not be porting the number directly to the provider, we want to retain the number.

So calls will come in to us, but then we need to immediately forward the calls to an external number. 

What's the best method to do that?  I'm thinking just a translation pattern built in CUCM?

Translation patterns are for internal use to manipulate a number and then a route pattern will be responsible for pushing it out the gateway or some other method.  If this DID is still being sent to you you could either manipulate this at the CUBE and hairpin it backout or send it to CUCM and hairpin it back after it gets translated with a translation pattern out a route pattern.  I would recommend doing everything at the gateway unless you want to keep some record that the number is in use which CUCM can do more effectively.

This DID being used for a fax is elsewhere offnet at this point I take it?  Make sure you have the proper CSS's and partitions set for hair pinning if you do this on CUCM since by nature forwarding to external numbers is disabled by default (or at least it used to be as I recall).

Thanks.  Yes, I prefer CUCM (vs Gateway) so that everything is centrally configured, logged, etc.

I'll apply the correct CSS and partition to the translation pattern, test, and let you know.

Thanks!
