asterisk users - Mar 2008 - RTP Payload Problem

Hello,

My provider has told me that I need to change the RTP payload time to 10
milliseconds instead of the default of 20 to make their RTP packet
communication work.  Is there anyway to do this in Asterisk?

Also, what does RTP payload mean and why would it effect the sending of RTP
packets?

Thank you,
Mords

Sure, in sip.conf just define the codecs like this:
allow=ulaw:10   ;This means ulaw will use 10 millisecond frames for example.

It only works if you have Asterisk >= 1.4

If you are running 1.4, check rtp-packetization.txt under
  doc/ directory from source distribution.
