Hi!

I am using OpenSer with two Asterisk-b2bua

Sip client<--------->OpenSer<--------------------->Asterisk-b2bua<------->PSTN
                                |
                                |
                                <----------------------------->Asterisk-b2bua<----------->PSTN

In OpenSer configure file  I am using  ds_select_dst("2", "4"); to perform load sharing the calls to PSTN.
But when Sip client hang up first, I don't konw how to make OpenSer forward the Bye message from Sip client to correct Asterisk-b2bua to hang up the call at PSTN side.

Can any body can help me.

Thanks and best regards
