I'm new at this, but I think i'm missing something i should see, but I don't. Anyway, I have 3cx installed with a Linksys SPA-3102, a SOFTphone (ext.101), a linksys SPA-841 (ext. 100) and an analog phone on the SPA-3102 line 1 (ext.102). All are registered and showing a green light. I created an outbound prefix of 9 to access an outside line. Cannot call out at all, i get the following messages: Call(C:1B) is rejected: User Not Found 22:48:26.575 StratInOut:nCancel Call(C:1B): Call from Ext.100 to 8677008 terminated; reason: User Not Found 22:48:26.465 Endpoint::findSource Can not find source by following specs: Contact IP: '188.8.131.52'; From: '10000'; To: '8677008'; Rline: '8677008'; Contact: '10000' when I try to call the analog extension from any internal phone, I get "proxy authorization required, and the following in 3cx: 23:18:02.746 CallConf::Rejected Call(C:24) is rejected: Proxy Authentication Required 23:18:02.746 StratInOut:nCancel Call(C:24): Call from Ext.101 to 102 terminated; reason: Proxy Authentication Required 23:18:02.543 CallConf:nIncoming Call(C:24): Incoming call from Ext.101 to sip:email@example.com 23:17:25.137 CallConf::Rejected Call(C:23) is rejected: Proxy Authentication Required Please help!
