[Asterisk-Users] Qualify Frequency

[Matthew Boehm]

How frequent do the qualify packets go out?

I've got 5 phones at a remote location with ADSL and their qualify is 
set to 5000.

I've noticed that they will go "UNREACHABLE" and then immediatly go 
"REACHABLE" within a second or two.

We have this theory that the ADSL link (SBC) "caches" its route to our 
network (where Asterisk is) and so we get bad ping times while the route 
is being re-cached.

We'd like to be able to increase the frequency the qualify packets go 
out to keep this "cache" alive.

Any thoughts?

Thanks,
