Extention mobility over expressway

We have upgraded to CUCM 11.5, UCCX 11.6 and our Expressway is v8.9.

We understood that this would allow the ability to log into Extension Mobility while a telephone (8851) is remote.  However when we do this we receive a 404 page not found error.

Is this a situation where a port needs to be opened on our network firewall or is there something within our system that needs to be fixed? 

We are trying to identify a remote call center agent solution and the ability to bring the phone home was one of our ideas.

Re: Extention mobility over expressway

Thank you very much Ratheesh, greatly appreciate the information.  Is the upgrade to Expressway relatively easy, does it entail rebooting CM and/or UCCX as well as Expressway?

Re: Extention mobility over expressway

Fairly easy but you need to keep up with Expressway updates as you would any other directly internet-facing system. For example, they patched seven CVEs between X12.5.1 and x12.5.2 alone.

You should be able to make it to X8.11 as-is. The jump to X12.5 will require an option key to validate you still have active support.

As always, keep an eye on the release notes. The main gotcha is the requirement for A and PTR records - including the public IP address. Unless you have your own prefix delegation this typically requires the cooperation of your ISP to get the public PTR created.

Have you allowed the Extension Mobility webpage though the Core?
