3905 and CME 9.1

[Victor Emmanuel Garcia Ruiz]

Hi!

I need some help with 3905 SIP phones and CME 9.1 (2911 Router):

* I read that conference in this phone is supported, but I can't find how to set the conference up. There isn't a dedicated key for conferencing and when I'm in a call there is no options available in the menu.

* For some reason, the phone loses registration with the CME and the only way to get it back is unplugging and plugging it back in to the switch.

Even if I restart the Router, the phone still shows its label and if I off-hook it, strangely gives a dial tone. When the Router is back the phone don't try to register again until it's restarted. ¿Isn't there a keep alive for registration with the CME?

Thanks for your help!
Best regards.

P.S. 3905 firmware v9.4.1

Hi Manish,

I had read that post before, but the "phone locking" wasn't resolved. I've read there is a similar issue with traditional CUCM, where the 3905 phone doesn't realize that the CUCM are gone and therefore doesn't switch to SRST mode until it's restarted. I didn't find a workaround either.

And the issue with the conference is more simple: I just don't know how to start a conference in the 3905.

Any help? Regards.
