Does Xfinity support Session Initiation Protocol (SIP) for IP phones on residential service?

SIP phone drops connection after 30 seconds on outgoing calls only.  Does not drop connection on incoming calls.

 

I rebooted the router, reconfigured the router, Comcast replaced the router still not working and no explanation why not working.
