I am new to IP-PBX and VoIP. I have installed Elastix 1.3 and configured a trunk for VoIP account with Oztell and Pennytel. I have 2 incoming numbers with Oztell. When i try to connect using "BOL SipPhone" directly to Oztell I can connect without any problem and receive incoming and calls and make outgoing calls. But, when I try to use the PBX, i cannot make or receive any calls. I have spoken to Oztell; they can see that Elastix is connected to their system. I have 2 extensions configured on PBX and connected using "BOL SipPhone" and they normally work fine if i call internally. I have opened the UDP ports 5060 and 10000 to 20000 for the PBX but still can't receive any incoming calls. When i check the FREE PBX, even that shows 2 trunks online and 2 registrations plus 2 IP phones. IP Phones Online 2 IP Trunks Online 2 IP Trunk Registrations 2 Server status for everything is OK. Asterisk OK Op Panel OK MySQL OK Web Server OK SSH Server OK But when i go to the DASHBOARD in ELASTIX, it says that I haven't extension. But, it does show the extensions and the trunks in green under "FLASH OPERATOR PANEL". I tried to configure a ring group and added both extensions and a mobile number in it. But when i try to use that Ring Group in the "Incoming Route", ELASTIX doesn't say anything but in FRE PBX it comes up with an error "There are 1 bad destinations" When I try to dial out, I get a message "ALL CIRCUITS ARE BUSY, PLEASE TRY AGAIN LATER" Please advice on what should or can I do to fix this problem. Any help will be much appreciated.
