Hi all, I have few issues that i need help with. My configuration are a follows; I have the free 3CX PBX on WinXP Server a Linksys SPA-3102 VoIP gateway one Traditional Phone (PSTN) a VoIP Provider SIP account a DIDWW ibound number a Grandstream 4 lines GXP2000 (HW1.2B) a Dlink DIR-625 router I set up 4 extensions, one on my laptop (3CX Client), one on Linksys SPA-3102 VoIP gateway (User 1), two on the GXP2000, I set up one VoIP Lines I setup one PSTN Line I mapped my inbound DIDWW number to my VoIP SIP Account I set up tunnel on the 3CX PBX I am using a FQDN to reach my 3CX PBX Server. The Dlink router Virtual server and firewall is setup to allow all ports thru and working okay. No to my issues............ 1st Senerio: All devices in my Local LAN. I can successfully call and recieve call on every 4 extensions. All extensios registered with 3CX PBX. Tunnels establised. When i used my cellphone to call my VoIP DIDWW number i recieved it as expected on my extension and it shows the CALLER DISPLAY. When i used my cellphone to call the PSTN number i recieved the call as expected however the CALLER DISPLAY shows the PSTN Extension number "10001" rather than the caller Number and name. HOW WILL I CONFIGURE THE PSTN RECIEVED CALLs TO SHOW THE CALLER NUMBER AND NAMES ? (if i conect my phone directly to the PSTN line i see the names and numbers). ALSO, If i call out using the VoIP LINE i will line my DIDWW number to show as well as my Name. How will i configure the VoIP Line to send that info. When my route use the PSTN line it does showsmy name and number. 2nd Senerio: when i move my Grandstream 4 lines GXP2000 phone to the front of my DLink router (remote-extension) the extension registered and i can make calls from the phone however it will not recieve calls. When i move my laptop to the internet (remote-extension) it registered, can make and recieve calls. I try to install the 3CX client on my PBX server so that i can set it up as proxzy but it always crash hence i have to uninstsall it. Last Question How can i recieve fax or does the free PBX version not support fax ? Any Quick help will be appreciated.
