[cisco-voip] Application Dial Rules equivalent for SIP URI dialing devices?

[Lelio Fulgenzi]

Yeah – I was thinking SIP route patterns as well. Was hoping there was another easier way. I’ve built “loopback” SIP trunks back to the cluster and tested that without issue, so it _should_ be ok. Might be worth a try.

As far as sending calls up to and back from VCS (or Expressway in my case), I was hoping not to have hair pinned calls, but, it might be ok.

The biggest issue is PSTN access. I didn’t mention that part. Some directory entries are PSTN numbers, not extensions. With the application dial rules, the transformation happens first, then the person dials and their personal CSS either allows or doesn’t allow.

First, I’ll try a SIP route pattern and see how that goes.

SIP Route patterns come to mind; you’d have to get creative with RegEx to create more specific matches for the shortened numbers though and it won’t scale well.

If you’re looking for true SIP transformation behaviors, you’ll probably need the assistance of a SIP proxy; VCS comes to mind. Send the dial up to VCS, match & transform and then match the transformed dial to the CUCM neighbor. This is the same way you’d do an internal video call between two clusters using VCS, except in this case your calling and called cluster is the same.

I believe that technique requires a non-traversal license for each call and a think it used to be free on VCS, though I must say I have not tried it recently and that may no longer be the case.

OK – more CE 9.4 fun.

We have a legacy issue that we use Application Dial Rules to get around when using Jabber, but it seems that V/C units that dial a full URI regardless of DN entered don’t use these rules.

For example, the directory lookup shows lelio’s telephone number as +1-519-824-4120 x56354. The Application Dial rule finds and strips out everything before my extension and it works. Wow!

But my SX20 dials the whole string +1519824412056354 at acme.com<mailto:+1519824412056354 at acme.com>

I want to be able to strip out the beginning and dial just 56354 at acme.com<mailto:56354 at acme.com>

What options do I have?
