<extension>@<ip address> calling on CUCM

[Laszlo Olah]

Dear Colleagues,

I have a CUCM registered DX80 and I would like to call some partners by <extension>@<ip address> format.

I thought that the * or *.* SIP Route Pattern matches to this format, but it does not.

Is there any way to achive this kind of dialling?

Thanks in advance,

Laszlo

Yes, but you'll need Cisco Expressway/VCS in your environment with B2B video configuration and licensed for Rich Media, do you have it?

Hi,

Yes I have these and I successfully setup the IP calling.

I have problem with the <extension>@<ip address> calling only.

Thanks,

Laszlo

Based on a Cisco documentation I have implemented the scenario below:

1. The user calls the 8378@109.239.231.232 address by the following format: 8378*109*239*231*232

2. The !*!*!*!*! route pattern forwards the call to Extpressay Control

3. On the Expressay Control a transform rule will change the string back to <extension>@<IP address>

• Pattern: (\d*)\*(\d{1,3})\*(\d{1,3})\*(\d{1,3})\*(\d{1,3})(.*)
• Replace string: \1@\2.\3.\4.\5
• Transformed alias: 8378@109.239.231.232
