Does Cisco SPA7940/7941 IP Phone works with third party open SIP server? http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=2521548 2013-05-23T01:44:04Z 2013-05-23T01:44:04Z Giggesh Thekkekeloth http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=2567356 2010-09-23T20:38:45Z 2010-09-23T20:36:34Z

Hi,   AFAIK, integration of 7940 IP Phones with third party SIP call manager is possible. I believe, you would have to use SIP/MGCP firware version of IP phones to achieve this.   Further reference on this from http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7960g_7940g/mgcp/firmware/matrix/frmwrup.html   The Cisco IP Phone 7960 and 7940 platform has the ability to support three protocol application firmware versions: >SCCP - Used with Cisco Call Manager. >SIP - Used with Cisco SIP Proxy Server (CSPS), base transceiver station (BTS), third-party servers, or as a standalone entity. >MGCP - Used with third-party call agents (CAs).

Hello Cisco experts,   We are manufacturer of SIP Call Manager. Our customers are highly demanding Cisco 7940/7941 IP-Phones to work with our SIP call manager. I would like to know if Cisco 7940/7941 IP Phones support firmware for standard SIP interface (RFC 3261 and others)? If not, what is the way to integrate 7940/7940 IP Phones with third party SIP call manager?   -Vivek Batra
