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.

I'm getting the captures right now.  One thing I did find out is that if
you don't end up with the same codec in and out, you only get one of the:

    -- Got 0ms silence< 700ms required
    -- Got 0ms silence< 700ms required

instead of both of them.  :)
