1) I don't see a point in changing firmware to SIP. The native firmware 
is still SCCP, and AFAIK it still offers a bit more than it's SIP 
2) Seat licenses will cost more with third party SIP phones. On the 
other hand, since Linksys's voice line has been more or less integrated 
into the Cisco offer, it's future support is questionable at least (no 
point in running competing products, right?)
3) You need to buy separate MCS for IPCCX (or rather UCCX as it's called 
nowadays). UCCM 5.x+ does not support any collocated applications anymore.

.. just my 2c.
