Summary:                    [patch] chan_sip fails to destroy channels in INVITE
when no response received
Description: 
In the event that a call is made to a device that is not responding INVITE
packets are reliably transmitted to the device, if the call is hungup the
channel lives forever.

There is still an issue relate to this patch. Some ACK's are never killed
like those INVTE's. For example, right now it is 2:30 AM and there has not
been any calls since a few hours ago, but I see dozens of lines like this
this when I type "sip show channels"
208.78.161.210 3864922293 790a13246b2 00103/00102 0x0 (nothing) No Tx:
ACK

of course "core show channel"s shows nothing. Linux shows UDP ports still
in use.
