    Conversion error from Elastix 2.5/4.0

    I'm trying to convert an existing Elastix configuration to 3cx (Elastix 5.0). I've uploaded the file 2 days ago, but never get a response (with sure not in spam). When I try to upload it again I got an error that configuration is already converted. What should I do ? Is there a way to convert...

    The customer said that port 5001 was blocked, it is now enabled, but still MCU list is empty (after services restart). They are checking now firewall settings (point 2). Point 3 should not be the case.

    3CX through MPLS or VPN

    Also, replace IAX interconnections with 3cx bridges, 3cx tunnel is very similar to IAX, the port is TCP/UDP 5090 instead of the 4569 used into IAX (for configuration of the firewall).

    Solved Eleven days with no Call Logs

    Fixing issues from SP2 took 3 months to complete. So you probably can't expect sooner response. I would recommend downgrading to SP2 or better even to SP1, if you have backups with configuration of the PBX from these SP. It is not recommended or not possible to downgrade to previous SP using...

    3CX through MPLS or VPN

    If your setup is working with FreePBX/Asterisk, there is no reason not to work with 3CX. Just create the same extensions with same password and use the same IP address for your 3CX system and phones will register to 3CX. No changes required on your firewall, the only difference is that 3CX uses...

    Solved Hotel set-up

    There is no problem of using Cisco SPA8000 as FXS gateways, you need to configure them manually, very similar to SPA2102 or newer SPA112/122. There is no conceptual difference between 3CX and FreePBX/Asterisk in using SIP devices.

    Hosted Server / SBC confusion

    I would rather rethink the networking model / hosting and use VPNs. Much more reliable than SBCs for quotes size of sites, regardless of improvements in SBC.

    Fax Caller-ID not working

    Ok, what combination of outgoing parameters should be used in order caller-id set into fax extension settings to be used -- I tried originator's caller-id, also caller-id taken from extension settings, but unfortunately without luck. If no caller-id is set into fax extension, then the sip...

    3cx free edition

    The old scheme until v.15 was better -- there was a demo key non-expiring, which was unlocking 2 SC pro edition -- enough to test full functionality of the PBX or use it at home. Can't you revert to this model instead of the whole mess with PBX edition (gone, sake God), free annual standard edt...

    Fax Caller-ID not working

    Previous topic was closed with statement that issue is fixed .. Unfortunately still exists (SP3) and is causing problems with billing and similar. I have a customer -- a shopping center and some of the tenants are still using faxes, so the management of the shopping center needs precise...

    Where can I find an SP2 ISO?

    You should be able to afford paying maintenance or renewing annual license, so use the latest SP3 instead. It has more features and is performing better. Also you can't restore a newer backup to older 3CX version, even you have found the image.

    Regardless of setting Caller-ID for fax extensions and settings of outbound parameters for SIP trunk -- the desired Caller-ID is not send / used, instead caller-ID of the SIP trunk is used. Tests include setting of Originator's caller-id and caller-id taken from extension setting for Contact...
