SIP and Communication Manager?

[glenng3]

The boss is looking at a new Polycom SoundStation 6000 SIP conference phone and wants to know if we can plug it in just like the 4610SW IP phone on his desk. "No," I say, "We don't have an SES server." "Look," he says, "If I configure the 4610 to use SIP it still works!"

So what is really going on with the 4610? Is it using SIP even though we don't have an SES server? Our system is a Definity G3si, R013x.01.5.642.3 = g3v13 CM 3.1.5 = Communication Manager 3.1.5. To further confuse matters, we do have SIP trunks set up between the 8500 media server and a separate 8500 Expanded Meet-Me Conferencing server.

Thanks.

glenng3,

SIP endpoints require a Session Manager/System Manager server configuration to work. We use Polycom Soundstation 7000s that register to our SM server and get their firmware and DHCP from a web server. The Soundstation 6000 is a SIP phone so I do not understand how you got it to register as a SIP endpoints without Session Manager. I would check to see if the phone is registering as an H.323 endpoint by "list registered-ip-stations".

His 4610SW is running an H.323-based software load.

I believe you're right, gwebster. I ran a "list registered-ip-stations" and the boss's phone was right there in the list with all the other phones. Probably even if you tell the phone to run SIP, it connects using whichever signaling protocol is available.

 

[gwebster]

H.323 and SIP are two entirely different software loads on the 4610SW. You match the software on the phone to the required signaling protocol. In your case, it has to be H.323. There is SIP software for the 4610SW but - as others have said - you need either SES/SM to use it.

You can use SIP-based phones e.g. Polycom 6000 without a session manager, but you need *something* to which the SIP-based phone can register. For example, I've set up a FreeSwitch, registered SIP phones to it, and connected it to the Avaya. The phones looked and behaved as if they were on the Avaya. (There is another thread on this forum where I put a sample freeswitch.xml that would accomplish this)
