I have got Voipbuster with a inbound number. Because i did not know anything about a good PBX for Windows is recently use Asterisk in Linux wich i got working fine. Since iam always looking for something news (and easier) i installed 3CX. So here's the problem i have got: I got the thing working with the VoipBuster account, iam able to dial outbound numbers but my voipbuster outbound numer is not displayed. Inbound numbers wont pass thru to the setup user.... Iam using Eyebeam for testing. Dial Outbound: Registration of sip:Motormuisje@sip.voipbuster.com is successful 08:13:26.390 StratInOut:nHangUp Call from Ext.1001 to 0031314365*** has been terminated 08:13:16.843 CallConf:nIncoming Incoming call from Ext.1001 to sip:0031314365***@localhost 08:12:10.843 ServRegs:nAdd Registered: Ext.1001 That part is working but the number is not displayed in the phone of the dialed number. From outbound to 3CX: 08:20:35.593 Endpoint::findSource Can not find source by following specs: From: '0031314365***'; To: 'r.kruissen'; Rline: 'r.kruissen'; Contact: '0031314365***' Any suggestions ???
