Do You know what is the TCP port number of VoIP traffic ?

Because I am configuring two routers connected by frame relay with two dlci

one dlci for data and the other one for Voip traffic.


My plan is, if i knew the port number of voip traffic then i will filter out certain traffic from one interface.
