Summary:                    [patch] pri early media won't ring
Description: 
hi:
   our asterisk connection like below:
   <sip or iax phone>---<asterisk>---<alcatel pbx>---<PSTN>

asterisk connect to alcatel pbx via E1 isdn-pri
 
   when sip phone (snom 300) or iax phone (zoiper) call PSTN, they can not
hear the ring tone and the beginning of the PSTN voice.
   I have checked issue 18868 and tried below combination with no luck.

   1.8.3.2 + sig_pri patch
   1.8 svn which already has sig_pri patched
   1.8.4 + libpri patch (another unofficial patch in issue 18868)
  
   I downgrade to 1.6.2.18 and I found everything works fine.
zoiper iax is ok and after setting "prematuremedia=no",snom sip phone is
fine too.
 
   I don't what other options to try. or what debug information to
provide. please tell me if necessary.

PRI early media won't ring.

And another way to pass early media.  Don't indicate that there is inband
information present, just assume that the B channel is connected.

* Restore clearing the dialing flag Rx squelch unconditionally when a
PROCEEDING message comes in.
