Dear all.
After comparing between the same digit sent in one session to the SIP server
(asterisk) by X-lite (Softfone) and SIPp i found some differences here:
the time duration of continuous packet in one time press (in my case, that
is number 7 )
X-lite : 160 - 320 - 480 - 640 -800.....(adding 160 after one packet)
SIPp : 0 - 320 - 640 - 1280..... ( x2 after one packet)
* *I think that's the reason why Asterisk doesn't recognize the pressed
button.
Any ideal on fix the duration ( as refer at 3.5 at
this<http://www.ietf.org/rfc/rfc2833.txt> it's timestamps
of packets)
many thank, if you know , please help...
