[asterisk-users] PJSIP hints unreliable...

     I find that using hints with PJSIP on Asterisk 13 is very 
unreliable compared to regular SIP.  I see many phones as unavailable 
when they are in fact available.  Usually hints will work fine for a 
while after a phone registers but after a while it will remain at 
unavailable while it is idle.  If the phone is in use I will get the 
correct status from the hint (InUse, OnHold, Ringing) but it will go 
back to unavailable after ther call is done.

     IAX2 endpoints do not have this problem and their hints work all 
the time.  Since moving to PJSIP we are registering several devices 
using the same account and I find that these endpoints tend to dissapear 
from my console after one of the devices unregisters even though there 
is still another one active.

     Any recommendations or configurations needed to stabilize hints for
