I m monitoring voice traffic by using sPan on the switch.

when the iPPhone 7941 register on the CUCM 7.0 , i get this message on the wireshark:

S10930 210.718051 192.168.100.42 192.168.100.1 SKINNY RegisterMessage

This is just an SCCP registration message. The reason the DeviceType is showing up as unknown is just because wireshark doesn't have a decoding filter for that DeviceType value (115). You'll see different things in different sniffers depending on how current the programmers are on SCCP messaging and DeviceTypes.
