On dashboard, I chose Client media - Redirect Media, I got
following:

In AES DMCC Service Summary - Device Detail
I got:
Device Id: 6449:S8700:172.16.3.204:0
When Registered: 17, 2010 12:58:56 CST
Time Since Registration: 0 hours, 5 minutes, 41 seconds,
Media Mode: CLIENT
Dependency Mode: DEPENDENT
RTP Address:Port:
RTCP Address:Port: /10.236.0.219:4726
Encryption Parameters: none
Codec Parameters: g711U
Number of Associated Sessions: 1

I didn't succeed in changing the RTP port.
Please help , thank you.

What release of AE Services?
What DMCC SDK?
What SDK release?
What media mode are you using?
On an active call or while idle?
What does the dmcc-trace.log.0 file show as it processed your request?
Are you still receiving RTP at the prior IP/port address?
Does the SAT Command 'status station 6449' show Communication Manager has redirected the media?
Does Communication Manager throw any denial events in the interval that it is processing your request (SAT: clear events, run test, SAT display events, type=denial)

According to the RTP RFC, the RTP port address is always an EVEN integer (2N), and the RTCP port is always the next ODD integer (2N+1), which is not what your request contains.

AES : 4.2.2
DMCC SDK 4.2.46/ Dashboard 4.2.46
media mode: Client media
I made redirectmedia on Client Media page in Dashboard while idle.

I made a new try (rtp changed from 31000 to 32000)

the SAT " status st 6449" doesn't show any RTP info.
and the ' test st 6449' shows all passed

you need to have an active call for status station to show RTP media info...

Increase the tracing level so you can see the XML handling so you can at least tell when the redirectMedia was processed in the mvap-trace.

Are you still receiving RTP at the prior IP/port address?

Does Communication Manager throw any denial events in the interval that it is processing your request (SAT: clear events, run test, SAT display events, type=denial)

What Communication Manager release are you running?

How are you verifying that Communication Manager changes the RTP media destination? Are you attempting to do a dynamic mid active call change, or testing making a change between calls? If mid active call, are you in direct media mode, or TDM media mode?
