All our phones are currently using SCCP and have been since we have been using Call Manager. My company has purchased some 8841s and 7841s, but I'm only seeing SIP protocols for them on 10.5.1.10000-7 of the call manager. I'm going to make an assumbtion here that I would need to add a device default with SCCP as the protocol. After downloading an SCCP file for this model. These phones don't offer a file to upload to have the SCCP protocol. Any help on how to setup a SCCP phone type for these models? Or would it not hurt anything to run them on the SIP protocol?
Solved! Go to Solution.
Sorry for being out of touch with this, so all the phones we have could support both. But these two models only support SIP. Can these be used on our system and what functinality would change? My understanding is that our gateway supports SIP.
In large part there is feature parity between SIP and SCCP phones. There is no reason you cannot run both protocols. Regardless of the protocol used on your gateway you can run both protocols on CUCM. SIP/SCCP are simply the protocols used for phone signaling on the two devices.
regardless of the protocol used in gateway, you would not be able to register those phones with sccp in ccucm as those are SIP enabled by design, refer the release notes fro the same.
nothing going to be changed in terms of funcationility as CUCM can do the interoperability as it understand SIP, SCCP, etc , you can have mixed of phone which support sip and sccp there won't be any issue .
