[cisco-voip] CCM5/6/Express with SIP or SCCP phones?

[Jozef Janitor]

Hello,

 

I have had bad experiences with SIP firmware on Cisco IP Phones (well, on
3rd party IP PBX), and I think it was already mentioned here in the list
that the SIP firmware is a bit "buggy".

But now I am facing a situation where we may have to deploy some Cisco IP
phones with SIP firmware with Cisco Unified Communications Manager (full or
express). Therefore I would like to ask you a question:

 

If you are running Cisco Unified Communications Manager 5+ or 6+ or CCM
Express 4+:

-          Are you using SIP or SCCP firmware on your Cisco IP Phones?

o   Why SIP

§  Pros?

§  Cons?

o   Why SCPP?

§  Pros?

§  Cons?

 

Thank you.

 

All the best,

   Jozef Janitor
