Hi,

In Cisco CME 3.4, support for connecting and provisioning SIP phones was added

Reference :- http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeadm/cmebasic.html#83077

and in Cisco CallManager Express 3.4 supported firmware,platform and voice products.Cisco ip phone 7905 and 7912 are supported by sip.

And ip phone 7910 is mentioned but for only SCCP

Reference : http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/requirements/guide/cme34spc.html

and for Cisco ip phone 7911 the firmware needs to be upgraded to convert to sip

Reference : http://www.firewall.cx/downloads/cisco-tools-a-applications/cisco-ip-phone-a-ata-firmware-downloads.html

            http://lodge.glasgownet.com/tech/upgrade-a-cisco-7911-to-sip-firmware/

To upgrade or CONVERT the phone firmware for a particular phone from SCCP to SIP, follow the steps in this.

If Cisco Unified IP phones presently connected to Cisco Unified CME are using the SCCP protocol to receive 

and place calls and you now want some or all of these phones to use the SIP protocol, the phone firmware for 

each phone type must be upgraded from SCCP to the recommended SIP version before the phones can register
