extension mobility does not appear on ip phone

[HatemCisco2010]

Hi Guys ,

i have a strange case on  a remote site .

In fact , when i connect an ip phone to a switch (2960)  on site B , the Extension mobility does 'nt on appear  when i press the services key .

However wheni connect the same ip phone to another switch it appears .

Did any one face this problem ?

What do you see when you press Services when connected to the 2960?  Is it on the same VLAN as the other switch?

Perhaps it cannot resolve the DNS of the EM service?

I  would suggest looking through the phone console logs for clues, you can  access the log by browsing to the IP address of the phone.

HTH,

Chris

Hi,

Also see if any kind of ACL is applied in the network path when you are connecting it to problametic switch.
