3CX & Gamma Help

[richbrowncardiff]

Hi Everyone,

 

Please can anyone who is using 3cx and gamma sip trunks give me some pointers ?

 

Gamma support have been appalling all i want is a few steps to getting their "Supported" sip trunks working with 3cx.

 

I have been told after 3 hours of back and forth they can see a private ip.

 

Can anyone let me know how I should set their trunks up in 3cx it should be simple (sipgate was) but gamma seem to not care about getting it working.

 

Many thanks in advance

Just heading down the same route rich but haven't got access to the server yet as our lead school is hosting it. We have an fttc for each site from gamma but the sip setup should be the same. If you haven't solved by the time I get access I will repost

We have Gamma working with 3CX.

 

I’m on annual leave at the moment but from what I can remember, we put the public IP into the options tab of the sip trunk and ticked Put Public IP in SIP VIA Header box to make sure it authenticated correctly.

 

There was some back and fourth action with our ISP for firewall rules but eventually got it sorted, needed to make sure the traffic leaving our 3CX was using the public IP provided to gamma rather than shared IP from ISP otherwise it just wouldn’t register.

Thanks for the info I have done this and its still not working. Can you tell me if you had to alter any of the strings on the "Outbound pentameters" Page?

Great, glad it worked.

 

I remember I had to try a few different options before I got ours working but has been brilliant since setting up, best thing we ever did.

At one point Gamma started getting an internal IP from me, turns out the Fortigate firewall had decided to "help" and rewrite the packets.

Thanks Very much for all the help much appreciated. I'm just shocked that this information isn't provided as 3Cx have template'd Gamma and visa versa.

 

In essence i expected to set the trunk up in 2 minutes just as I did with Sipgate. Oh well all good now thanks again!
