Curious to see what some other users and/or Cisco guys say about what they use or prefeer when it comes to what call protocol for different endpoints. It can be endpoints such as C-Series which can use both, or an MCU. We have a mix of endpoints ourselves that can either be configured with both protocols or some with just one type, hence the discussion to see what and how some others choose to configure theirs.
Ideally both the protocols can work fine on the device. There are some situations where having both protocols can prove to be of advantage. SIP is good for latency and to have very little overhead as compared to H323. If you already have H323 then you can configure SIP on the same device for the following purpose:
Hope this answers your question.
Thanks for the input, most of our endpoints are configured for H323, however we do have some that are using SIP (E20, Jabber). We've configured our VCS search rules to allow for searches in either direction and capable of locating either device with/without domain, however I'm looking into the prospect of trying remove that need. What does Cisco do for their H323 and SIP devices, and when it comes to the VCS?
I am afraid, I wont be the best person to comment on that. There are no recommendations as far as I know. We recommend the customers to keep the methods (H323 or SIP or Both) that they find suitable to be used in their network setup.
