The filter I was using  "udp.port == 56789 || udp.port 10476" was not showing RTP packets in the version of wireshark I was using (1.8.0). After I upgraded wireshark to the latest version it  did work.

<div>
<div class="content wysiwyg-content">
I have a SIP trace with about 7 active calls. I have identified a problem for one particular call and can see that the RTP streams that are setup for this call are using port 59290 to IP-address1 and 10476 to IP-address2.<br />
<br />
I would like to make a display filter for each of these RTP packet streams but this is beyond my capability to figure out do quickly enough (or if it can be done at all).<br />
<br />
Any suggestions? Here is the Wireshark display filter page for RTP<br />

Wireshark Filter for SIP RTP stream

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.

Telecommunications

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.
