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).

We have this bug on many sites too. Intersting that some sites (same xlite
version, same asterisk version) doesn't have the problem, but others do. I
still can't find the differences.

Only happens on new tags on 1.4. (1.4.26.2 sure doesn't have the problem
at all).
