Hi, i have a problem with outbound calls on pstn line. I'm using a Sipura 3000 gateway, 3CX Phone System v3.0.1699.0 and Cisco Ip phones 7960. Some outbounding calls (not all) over the pstn line are dropped after 32/33 seconds. Inbound and internal calls work perfectly. this is the server status log: 11:29:32.633 StratLink:nHangUp Call(C:98): got Hang-Up from Ext.207; reason: ??? 11:29:00.258 CallLegImpl:nConnected Established media channel for Ln:200@Sipura 3000: remote=10.0.0.4:16470; local=:17126 11:29:00.258 StratInOut:nConnected Call from Ext.207 to Ln:200@Sipura 3000 is established 11:29:00.258 CallLegImpl:nConnected Established media channel for Ext.207: remote=:17126; local=10.0.0.4:16470 11:29:00.039 CallConf:nIncoming Incoming call from Ext.207 to sip:011XXXXXXX@10.0.0.4 The mistake is that not all the calls are dropped, but i can't understand why!!! Any suggestions? thanks. Roberto.
