Extension Mobility Issue

On the 7961 IP phone, Login & Logout Extension mobility displays after pressing the services button. But when I press either option, it displays ?Host not found?.

Hi,

I tried configuring Extension Mobility on Callmanager 5.0 on 7961 & 7940 IP phones.

On the 7961 IP phone, Login & Logout Extension mobility displays after pressing the services button. But when I press either option, it displays ?Host not found?.

Hello,

I am almost sure you are facing a DNS problem here.

The EM application URL's use backreferences to the CCM server, and even if you configured the services to use IP addresses, the EM will use what it sees in the CallManager server configuration (hostname, FQDN).

If I were you I would try to sniff the TCP traffic on the phone and see what it is trying to use to connect to using HTTP.

Hi netbakter,

Thanks for your response, but I dn't think it's a DNS problem. Nevertheless, if I was to sniff the TCP traffic on the phone and see what its trying to use to connect to using HTTP, how do I go about the process of acheiving this. I'll appreciate your response. Thank you.

Re: Extension Mobility Issue

Hi there,

actually, are you able to open the EM URL in a browser (the same way as it is configured on the CallManager)?

If you want to set up sniffing, you may want to set up a monitor session on the switch where the phone is connected to and span the traffic to a dedicated switch port where you could intercept it. Watch for the traffic between the phone's IP address and the server's one.

Thanks for you response. I have checked the EM service URL and confirmed it's correct, but it's still the same case. Could there be any other way to rectify this issue?
