Cisco IP Phone Without CM or CME.

Hi,

I am new to IP Telephony, I am just wondering is it possible to run a Cisco IP Phone (7940G and 7960G) without present of any CallManager or CallManager Express?

I have heard from Cisco engineer from Malaysia that it might be able to work when using SIP protocol on the IP Phone itself.

Much appreciate on any advises.

Yes, a SIP loaded IP Phone can work with a 3rd party call agent.

Thanks for your reply. But I would like to apologize for not making things clear. Actually there are few Cisco IP Phones, a C3660 router with 4 FXS ports, an AS5350 with 4 E1 interfaces. All these connected to the same network segment.

The requirement is IP Phone call to IP Phone and IP Phone call to router FXS analog phones, and vice-versa, without a CallManager or CallManager Express. Will this kind off setup work?

Thank you.

Regards,

Wei Ming, Wong.
