A call from CUCM to SIP trunk, from SIP message captured on the SIP trunk, can I tell the call is from a SCCP phone or a SIP phone?

For some reason, I need to find out the end point point information from the SIP trunk. When a call from CUCM to SIP trunk, can I tell the end point information from the SIP message, e.g. SCCP phone or SIP phone? For instance, Cisco 8945 phone can have both SIP and SCCP firmware, so how can I tell the call is made from 8945 SIP phone or 8945 SCCP phone to SIP trunk?
