Is there a list of ports and Protocols for VoIP traffic?

Mike Clites

I am trying to verify that I have all the typical VoIP control ports/protocols as well as the VoIP stream ports covered in my Policy Map.

I am mapping the control packets as af31 and the actual Voice Streams ef on my outbound wan interfaces while respecting the markings on all the interior ports.

What I have been unable to find through google and browsing on my own is a list of the ports and protocols for a cisco environment deployed VoIP solution involving CUCM 8.5, Cube Router (sip gateway between inside and telco) in which we have a blend of all cisco phones running sccp & sip.

Can some one point me towards such a document or possibly even list them here?

Thank you in advance for any insights.

Why not using a Best Practice instead and set you policies based on the DSCP values that each packet carries already.
