CUCM and Cisco ip phones SIP Limitations

[youssef abdalla]

Hi ,

we have new implementation for CUCM and cisco ip telephony  project

and the integrator recommend to use sip for ip telephony

but now I m reading about some limitation for using sip over sccp , but  that in old threads cause I m not expert in ip telephony

so can someone advice me if there is really limitation in using sip over sccp for cucm with cisco ip phones ?

and if there is limitation what are the features that can not be used in sip while using sccp ?

All new Cisco phones (88XX, 78XX) are SIP only. Which models are you deploying?

With current version of CUCM the feature parity between SIP and SCCP is pretty much the same.

we have 7811 and 8841

Then nothing to consider here as these only support SIP :-)
