Hi,

I have somehow the impression that you are confusion 2 kinds of pinging:

1) in-dialog pining, controlled via the dialog module, completely unrelated to the LB module. This is done for each ongoing dialog.

2) failure probing, done by the LB module to the destinations/gateways which are mark as failed.

The 2 mechanism are completely independent.

The pinging 1) have the same call-id as the call they belong and goes as time as the call is up

The pinging 2) is not related to any call, have different call-id's each time.

Hi,

I am using opensips 1.9 with loadbalance module ,with dialog "/*create_dialog*/("/*PpB*/")"

I am facing a problem such when opensips try to send the call to gw1 and find that gw1 is not responding so it send it to gw2

In this case and when call connects , opensips will send a sip options ping to client with call-ID only and none to trunk gateway.

Meanwhile if gw1 is listening and opensips termonate the call to it and call connected it will send a sip ping options to UAC and to trunk gateway

Futthormore and as I know that opensips normally, should be sending option to gateways in the load balanacer table.

Please find below two links contains debug level 4 for the call scenario
