Summary:                    Asterisk causes crosstalk between inbound and random
channels
Description: 
This issue occurs approximately every 2 weeks.  A reboot of Asterisk seems
to resolve the issue for another 10-14 days.  There are no other related
errors, warnings or failures in the Asterisk logs.  ZTTOOL indicates no
alarms or issues with the PRI.  All vendors involved have checked line
attenuation to our demarcation point - passed without error.

When the following appears in the full log - the audio from this inbound
caller is broadcast to random channels: 

<snip>
chan_zap.c: Ring requested on channel 0/4 already in use or previously
requested on span 1.  Attempting to renegotiating channel.
</snip>

In the above example, this inbound caller was then negotiated to channel
0/5.  His/her audio was then broadcast to everyone in an ongoing
meetme-conference.  
Periodic automatic Zap clearing is set to 1800 seconds.
