Subject: [SIPForum-discussion] RTP Volume Values
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?
