Is it possible to use SCCP and SIP at the same time?

[bobdchambers]

Our CCM is using v9.1 and all of our phones are SCCP. We are looking at a conference room phone that runs SIP. Would it be possible to use this in our current setup?

Absolutely.   You can have a mixed environment.   You could flip your SCCP phones to SIP if you wanted.   In fact many of the newer Cisco endpoints only support a SIP based implementation.

Is there a way for me to test this before we actually purchase the phones? I don't want to convert all of our SCCP phones to SIP but maybe one or two just for testing.

Go to Bulk Administration -> Phones -> Migrate Phones -> SCCP to SIP.

Hi @bobdchambers,

That's totally fine. They both co-exist in the same environment but make sure to not configure the same extension in different models because if you dial an extension that is configured in a SCCP phone and a SIP phone, just the SCCP phone rings.

HTH.

There are no problems if you are using Cisco Unified Communications Manager (CUCM).

There are some problems with a mixed environment with CCME! As Mertin said shared lines and others.
