Summary:                    WaitForSilence() sometimes doesn't always wait when
using SIP and a callfile
Description: 
WaitForSilence() seems to always work when using a provider over IAX2 and a
call file, but doesn't always work with SIP providers.

For some reason, if I use Future-Nine to send the call out over SIP, it
works, but it fails to wait if I send the call over Callcentric (SIP) or
voip.ms (SIP).

If I send it over rapidvox (IAX2) or voip.ms (IAX2), WaitForSilence()
waits.

If I call the extension directly from a SIP phone (not using a call file),
it waits.

I've gone through my sip.conf many times, trying to see what the
differences could be, but I can't find anything that could cause this.

---------------------------------------------------------------------- 
This issue has already been fixed in later versions. It was creeping up
because app_waitforsilence waited for a small amount of time to receive
audio and if it did not it treated it as a hangup. In your case audio was
not coming in soon enough and this crept up. The code now requires an
actual hangup to happen and treats no incoming audio as silence instead of
hangup.
