IP Address Dial out from CUCM

[Nikhil Jayan Kandampully]

Hi,

I have MRA feature configured for CUCM and i have used my existing VCSC and VCSE for achieving the same.

CUCM: 9.1.2

VCSC & E: X8.1.1

what is the configuration i need to do in CUCM and Jabber Client for enabling the Public IP Address dial out??

is it supported from CUCM?

Thanks & Regards,

Nikhil Jayan

Hi,

If you are talking about Cisco UCM registered Jabber Clients being able to dial public IP address? this is something I am looking at now, still testing this myself but let me know how you go with it.

Make sure your clients can dial normal URI first so you know that part is working then do the following:

In UCM I have a SIP Route Pattern:

Pattern Usage = Domain Routing

Pattern = *

Trunk = VCS Control / ExpresswayC SIP Trunk

Users will need to dial address@ip example dial string would be 111.111.111.111@ip to route call to the VCS Device

on VCS Create a transform,

Pattern Type = Regex

Pattern = sip:(.*)@ip

Pattern behavior = Replace

Replace string = \1

That is exactly how I am solving the ip address dialing issue and it works perfectly.

One issue that I am having is when dialing a URI by ip address.

For example 12345@91.91.91.91 as opposed to 12345@acme.com

I cannot even to seem to pass this from CUCM to Expressway.

I tried adding a domain pattern of: *.*  but still no joy.

The search never shows up on Expressway.

FYI: CUCM 11, Expressway 8.7.3

Any thoughts?

John, take a look at the Dial IP Addresses from Endpoints Registered to CUCM with VCS / Expressway Configuration Example.

I have seen that document and it really only addresses dialing by ip address.  

I need alias@ipaddress.

I use option 1 for ip address only.  It works great. 

Option 2 is way too messy, especially with training users.  Can you say kludge?

But what I am not sure is why CUCM does not pass alias@ipaddress to Expressway when using * for domain pattern.

Thanks

Simple answer is CUCM does not support IP address dialing, even if you do try to dial alias@IP, it sees the domain as an IP address.  What if you try to dial IP@alias and then on the VCS/Expressway you create a transform that swaps it around to be alias@IP?

Still can't get it to route to Express.

Trying lot's of different combinations. No luck so far.
