How many phones in the remote location ?.

If you have more than three, I would be looking at installing SBC

Have you configured different ports for each phones - https://www.3cx.com/community/threa...etgear-nighthawk-x4s-d7800.54620/#post-225296

Hello @vipul zala

As @Saqqara suggested you will need to assign individual ports to each phone and port forward those ports on the remote firewall. https://www.3cx.com/3cxacademy/videos/intermediate/configuring-remote-extensions/

Thanks for the prompt reply @YiannisH_3CX & @Saqqara
i have more than 7 phones configured & each phones with STUN configuration with different port assign on each.
All our office branches are on remote location & i did configured everything on STUN & different ports for everything. i am having doubts on the Router coz we just have installed the Leased Line connection & i have configured it in the same router where they were using broadband connection before & its very basic model.
is that could be the reason ?

So you configured separate ports in both 3CX and forwarded them in your firewall?

 

[vipul zala]

@cobaltit yes i configured separate ports for each phone & after that i provisioned the phone by URL link.
That's what i did for all my branches & they work well i dont have to do anything in Router of respective office & they all have High-end router only this particular office where the Router is basic model.
Voice is coming late or even if i answer the call via hardphone other phones keep on ringing.

I would check the 3CX Activity Log, when one line picks up. You should see a series of 487 Request Terminated/INVITE from xxx.xxx.xxx.xxx:xxxx, with the the IP and local port of each set that did not answer. That may provide a clue as to why they are not reaching the sets

 

[YiannisH_3CX]

If your router is not configurable enough then i would recommend installing an SBC and re-provision the phones through the SBC to see if the issue is resolved.

Hi @YiannisH_3CX can you provide me a link for how to configure 3cx remote phones with SBC ?
i have searched online but couldn't find proper guidance.

You can pick between either windows or linux.
