Summary:                    [regression] X-Lite disconnects because of RTCP
timeout (see also https://issues.asterisk.org/view.php?id=17236 and
https://issues.asterisk.org/view.php?id=17559)
Description: 
I have upgraded from Asterisk 1.4.25 to Asterisk 1.4.35 and now i have
disconnection problems with X-Lite softphones making call through a Portech
MV-374 SIP/GSM gateway. If a call through a PRI card configured in the same
server the call is not disconnected.
This is the same problem of tickets
https://issues.asterisk.org/view.php?id=17236 and
https://issues.asterisk.org/view.php?id=17559 and for me is 100%
reproducible. I have tested also Asterisk 1.6.2.11 and i have the same
bug.
I have attached two full logs: one  of Asterisk with SIP history enabled
and one of X-lite. In these logs extension 201 call the number 3281234567
(i have replaced the real number..) and the call is hangup after 10 seconds
(in X-Lite i setup this time in the inactivity RTCP field, default is 30).

Okay, I have found the source of the issue for me.  When I put
'constantssrc=yes' in my sip.conf file this completely goes away.  Can
someone please verify this resolves the problem for them as well.

If this option is the source of the problem for you all as well, I am
going to investigate it further to determine if anything should be done to
the default behavior.
