Callpingserver/client

I have built a bandwidth on demand product for satellite communications, that incorporates an asterisk server/PBX at each site. All is working OK except for the chattiness of the IAX trunks between themselves. I have set the trunk messages down to 1 per second but the callping server continues to ping clients.

Should the call ping server ping all of the time, or should it only ping when registering with another IAX node or making a call? If it should ping all of the time, how do I set the interval?

Each of these pings initiates a carrier transmit sequence in the system.

Thanks for any help
