Unfortunately, I have not worked with any local partner of yours, and I don't believe there is a local partner in Palestine. Additionally, I am currently using the VitalPBX system and was interested in exploring the features of the 3CX system, especially since I am facing a technical issue with colleagues while using a third-party application like Linphone. A friend recommended that I try 3CX.
As you can see, I am encountering issues with the 3CX system's mobile application.
Hi,
in case this thread is still open /active // and it might be of interest?
- if you are trying to learn the basics of 3cx, then using a 'cloud hosted' (ie, public IP host / not behind a firewall) instance will probably be a path of less resistance than an on-prem install (ie, in your office behind a firewall)
- possibly the absolute simplest thing would be to try the "100% free SMB version" of 3cx which is hosted by 3cx, on your behalf, since this will minimize the amount of config required / the opportunity for config drama to cause unexpected issues. Once you do some basic 'kick the wheels' trial you have a better understanding of the product, with less time-effort required.
- if necessary you might have to buy a DID from a suitable VOIP_SIP carrier who is supported by 3cx. But this is arguably a trivial cost (a few dollars per month approx) to allow a test to move forward
- note also generally I would advise, in doing a test setup
-- get the free SMB version lit up
-- bind the SIP trunk
-- configure an EXT in the system, and do test outbound, inbound calling, via web-client agent first.
-- once that works, proceed to test from a softphone app client agent on smartphone (Ie, IOS or Android)
-- once that works, if desired, proceed with more traditional legacy handset voip phone config / possibly SBC integration needed. Or maybe just avoid this entirely

if physical handset are not really needed-wanted.
In theory there are partners available who could assist you / to move forward a 3cx trial project. I am sure such service is not free, but it would probably depend on the size / scope / intent of your project and how much support was required. ie, let me know if you need more help? at the very least I can provide some suggestions via the forum, and possibly more / if suitable and of interest.
(ie, I am not sure a partner must be geographically near to you in order to help)
Hope this is possibly of some use.
