Hi , i've a problem with the dispatcher module, for the load balancing for asterisk The schema of the network is this : Firewall (public ip: 199.199.199.199:5060) | | ------------------- Pc1 pc2 Pc1: 192.168.0.1:5060 Asterisk Pc2:192.168.0.3:5060 Asterisk Pc1:192.168.0.2:5060 Openser The ip public is natted with Openser The dispatcher.list is: 1 sip:192.168.0.1:5060 1 sip:192.168.0.3:5060 Openser.cfg: route{ if ((method=="INVITE") ){ ds_select_dst("1","4"); # 4 = round-robin t_relay(); exit(); } } In asterisk for test there is an ivr ,and when I make a call from an other site to this public ip, ast answer but after few seconds I see from the log of the pc01 the the call hang but from the remote asterisk (the one where I make the call) the call remain up. The configuration of openser is correct ? thanks
