[SIPForum-discussion] RTP Volume Values

[Zuñiga, Guillermo]

Hi fellows,

I would like you can help me with the following issue.
I am sending a DTMF event packet to a carrier and the carrier is just decoding the DTMF  for the first RTP and when I send the second RTP values doesn´t.

I am not clear with the Volume values, I was trying looking for information about this values and how is measured.
This value could be affecting that carrier is not recognizing  the dtmf?
Where I can find information about this value?
