[asterisk-users] Call drop-out on second incoming call.

[Mike Diehl]

Hi all,

I've got 12 Polycom 430's behind a NAT that are working pretty well except for 
one thing:

If one of my users is on the phone when another call comes in, there is about 
a 10 second time during which the user can't hear the call they're on.  Then 
it returns to normal.

My research indicated that I needed to add these setting to the phone:

========================================================
<CALL_WAITING tone.chord.callProg.6.freq.1="440" 
tone.chord.callProg.6.level.1="-19" tone.chord.callProg.6.onDur="300" 
tone.chord.callProg.6.offDur="100" tone.chord.callProg.6.repeat="2"/>

<callWaiting call.callWaiting.ring="ring"/>
reg.1.ringType="1"
reg.1.lineKeys="1"
reg.1.callsPerLineKey="3"
reg.2.ringType="1"
reg.2.lineKeys="1"
reg.2.callsPerLineKey="3"
========================================================

I've uploaded this config to the phone, but the symptoms persist.  Any clues?
