[Asterisk-Users] no audio between sip channels * 1.2.6

Sun Apr 2 10:38:57 MST 2006

Hello all,
I am running * 1.2.6 I have 2 linksys PAP2 with two phones each.  Until 
recently all was good.  on Friday I was running 1.2.5 when I added the fourth 
phone. I have to admit to initially wiring the rj11(crossed wires) wrong the 
first time but other than that nothing I can think of.  Added the appropriate 
entries in sip.con and on the PAP2.  I then tried to call from one line to 
the other and no sound.  Okay must have screwed something up.  checked 
sip.conf all looked good.  Okay good time to go to 1.2.6, still no audio.  
All phones ring and answer but no audio.  the last thing that apears on the 
console is "attempting native bridge of sip/677-xxxx and sip/699-xxxx"
below is a debug of a call and sip.conf.  Each channel on the PAP2's is set to 
a different port 5060 through 5063.  I can call in to any phone and all is 
good, use any phone to call to POTS line and back in on second POTS line and 
all is good.   I have been looking through the archive of the mail list that 
I keep and have not found anything to fix my problems yet.
i have transfered the registration of both PAP2's to a 1.2.0 system that I 
have and everything works as it should.  moved 1.2.0 configs to 1.2.6 box and 
again no audio between sip channels.
