Cisco Call Manager 11.5 Cell Phones

Can anyone point me in the right direction on how to configure cell phones to  use with Call Manager 11.5 ?

Can this be configured for use with or without VPN ?

I believe express way needs to be configured ?

Hi,
both methods can do the job:
- use of vpn
- ise of expressway without vpn

Which vpn type did you configure? Do you have wifi on your LAN to check if you are you able to register the iphone directly?

Anyconnect VPN, yes we have WiFi

We have a data WiFi no voice WiFi

I assume we need a voice WiFi

I configured this step by step via a Cisco doc, the doc seemed incomplete.

I am confused as to how the cell phone will get registered ?

I am also confused about the added benefit of adding cell phones ?

Our users have company cell phones and desk phones. it seems to me adding cell phones just creates another security hole.

What are your thoughts ?

When the cell phone is connected through vpn, try to check its IP address and try to ping it from your CUCM server.
In my opinion, using Jabber on cell phones provide flexibility and mobility for employees but nowadays, it is highly recommended to use expressway instead of anyconnect vpn.

Hello,
In order to troubleshoot the issue, we need to understand the whole setup, topology and configuration.
In all cases, here is a video created by a friend of mine that explains expressway implementation

Hope it helps.
