Summary:                    Prodding channel... causes 100% utilization
Description: 
from time to time, asterisk is locked (100% cpu utilization, but not crash)
with "Prodding channel..." messages...
grep "SIP/777-082ae2f8" /var/log/asterisk/messages | wc -l
856979

in my case it happened in entering simple diaplan, calling MoH...
 555 => { Set(TIMEOUT(absolute)=60); MusicOnHold(); }
user is connected over wifi, so maybe some packet was lost in some
critical call stage, that causes sip channel starts looping?

unfortunately, I was not able to do some debugging, because asterisk pc
was completely locked, due to realtime priority of asterisk process...

currently almost every call makes asterisk locks, as I posted before, 
disabling jitterbuffer has no efect,
often audible click in sound over iax
should I recompile with another debug options?
