Cisco NAM for Branch Routers is able to recognize IP telephony sessions in the
network by decoding VoIP protocols such as SCCP. With VoIP data collection
turned on, quality of calls can be extracted by decoding the VoIP control
packets. Analysis is available to provide granular details about each phone
session and system. Furthermore, in conjunction with using DiffServ (QoS), an
administrator can verify the QoS classes associated with the VoIP traffic. In
this scenario, some important questions that can be answered include:</DIV><A

<P><FONT face=Arial size=2>Hi, </FONT></P>
<P><FONT face=Arial size=2>I could`t find any information about RTCP reports on
IOS gateways apart from the command that sets the reporting interval.</FONT></P>
<P><FONT face=Arial size=2>Does anyone know how to:</FONT> </P>
<P><FONT face=Arial size=2>- enable/disable RTCP on an IOS H.323 GW?</FONT>
<BR><FONT face=Arial size=2>- Are there any Cisco Works products that can
receive the RTCP messages and create graphical reports? If not, then which
vendor`s RTCP server would you recommend?</FONT></P>
<P><FONT face=Arial size=2>- Is RTCP sent from every Cisco DSP board (NM-HDV,
PVDM, AIM) module for each tdm-to-voip call?</FONT> </P>
<P><FONT face=Arial size=2>Thanks.</FONT> </P>
