SIP blocking

Does anyone know if Comcast blocks SIP on business class lines? We had new business class lines installed but I can't get any of our IP phones to come online.

Welcome j1mat. Comcast does not block network protocols on our Business Service offerings. Please provide a little more information on the actual set up so that we may properly assist.

You stated that you had Business lines lines installed. Are you connecting via a Comcast Business gateway (SMC D3) or fiber on Business Enterprise? Also what interface device are you utilizing between the IP Phones and the Comcast network?

Thank you
