 For an IAX2 call, the answer is 'zero' for all of those call types (at
 least the ones that are supported in IAX2, not all of them are).

 For protocols that use RTP for media transport, two ports are required for
 each media stream (one for RTP, one for RTCP).

It certainly does. Whether it is accurate or not depends on the 
definition of 'call', as has already been pointed out in this thread.


I could also, definitively and accurately, state that the number of UDP 
ports required for a 'call' is 5 (five).

Why don't you make a call, and watch the network traffic with tcpdump, 
wireshark or similar? Wireshark in particular has an analysis module 
that will show you a summary of each network conversation by source and 
destination IP and port and protocol, as well as a handful of analyzers 
developed specifically for IP telephony. You can then count for yourself 
how many ports are used for your particular definition and 
implementation of call, as well as gain a deeper understanding of what 
happens on the wire.

Voice call *How many port of UDP or RTP ?*
Video call *How many port of UDP or RTP ?*
Fax call*How many port of UDP or RTP ?*
T.140 text call*   How many port of UDP or RTP ?*

As per the reply Voice call is come to 4 ports but rest is not clear.

Voice call *4*
Video call *??*
Fax call*??*

It is clear that you are lacking some basic understanding of how SIP and 
RTP operate; I would suggest that you take Phil Frost's advice and use 
Wireshark to watch what actually happens when you place calls on your 
system.


Just some points: UDP and RTP are not exclusive; RTP operates over UDP. 
Voice calls do not require 4 UDP ports (in most cases). FAX calls rarely 
use RTP.

Without understanding how they work, an answer to your question can't
be provided.  Or more succinctly, you can't formulate a question that
gives you a useful answer.

Maybe we can start with a more basic question centered around exactly
what you are trying to do and why?  Is the reason for asking because
you want to know how many ports to allocate in a NAT router, for
example?

 If you mean a voice call, it appears that each host must open three
 UDP sockets:

 - One to send/receive SIP commands
 - Two to receive sound (one for RTP, one for RTCP; The first port is
 even, the other is odd)


This is I think the best answer provided to you so far. The simplest and
most relevant I should say. Just to add to that, first port is TCP port and
the other two are UDP ports assuming you are using SIP protocol.

 SIP is most commonly transported over UDP, not TCP.

And probably doesn't really answer whatever it is that he really
needed to know or do, since how many ports doesn't seem like
anything that would be a useful thing to know.  Call it SIP trivia.

For protocols that use RTP for media transport, two ports are required
