External URI dialing configuration help

[Samuel T Mathai]

Would like to get help for configuring external URI dialing. We had implemented IM Presence 10.5 , cucm 10.5 & expressway c & e & we had CUBE routers. I heard we can setup sip route pattern for URI dialing. Did anyone tried this or give me idea how its works.

Yeah its definitely possible, there are quite a few things to configure and set up such as, srv records and externally signed certificates

start by reading this

https://www.cisco.com/c/dam/en/us/td/docs/telepresence/infrastructure/vcs/config_guide/X8-1/Cisco-VCS-Basic-Configuration-Control-with-Expressway-Deployment-Guide-X8-1.pdf

basically how it works is that external parties can dial straight into your organisation, for instance some one can dial jimbob@heinekenbeer.com    what you will need to remeber is that on your phones it is best to set up alternate numbers on each phone so the URI jimbob@heinekenbeer.com can actually be called.

Hope this helps

do we need configure federation for this ? I think we need rich media license for this too..right ?

[Dennis Mink]

Federation is not a requirement, and rich media licenses?  not really, we have it deployed in our organisation without them.

[Samuel T Mathai]

without license you can make calls to external URI dialing  (other domain name example like 123@cisco.com) ?

[Vivek Batra]

AFAIK, this is not licensed feature and hence you can.

thanks all.. I have done this successfully. B2B calls are working great. for b2b calls we need rich media license..  I have one issue with incoming uri dialing. example if some one made an incoming call to sam@cisco.com and my uri address is configured like Sam@cisco.com (capital letter S) call manager reject this call.

Hi,

Please check the following enterprise parameter and configure accordingly.

URI Lookup Policy - Case Sensitive/Case Insesitive

could you please share the configs ?

[Vivek Batra · Accepted solution]

Within a cluster, URI dialing only needs a valid URI to be map with one of phones DN, which can be dialed either though speed dial button or through Jabber.

Between the clusters, you would like to see ILS service for exchange of URIs between the clusters.
