Outbound call

[Ghazi]

Dear Friends,


Inbound calls working very well but the outbound not working at all I tried many rules.

Call to T:Line:10000>>077xxxxx778@[Dev:sip:[email protected].:5060] from L:52.1[Extn:100] failed, cause: Cause: 404 Not Found/INVITE from xx.xx.xx:5060
[CM503003]: Call(C:52): Call to <sip:[email protected]:5060> has failed; Cause: 404 Not Found/INVITE from xx.xx.xx:5060

Is the X'd out IP that of your provider? If so, then they don't seem to like something you are sending, or you are sending to the wrong IP. Who is your provider, or, is this a gateway?

This is my public IP and the internet provider make the port forwarding

I got this error today when I tried to call

Without additional information, I'm just guessing, but it could be an outbound rule, or the destination is not registered.

Did you read this https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/ about providing information, about your setup.

I hope this information will help you to understand the issue

So you are using a hosted system, and trying to send calls to a local GSM gateway. That explains a lot. This sort of configuration is not supported by 3CX. However, that is not saying that it will never work, just that it is going to have issues in getting outbound calls (especially audio), to the gateway, as you've discovered. Using VPN, would be one solution.

I read this post before,

the internet provider forward the port and every thing looks fine, and I'm testing just in one sim card.

when I change some rules sometime I head mobile provider voice when they say the number you have call is not in service and sometime doesn't exist

So, to start with, I now assume that this is a call back to your public IP (router). That being the case, the gateway should probably be provisioned to use some ports other than 5060, 5061, etc., as those may be used by another device on your network, especially as you are using STUN, requiring each device to use a unique local port.. Any ports you do use would have to be forwarded to the local IP of the GoIP gateway. And while that may get the signalling part to go through, but there are still all of the voice ports to get sorted out. Calls may complete, but you may not have any audio in one direction.

You must also make sure that you are sending a number, in the correct format, for the provider. Just as you would dial it from a mobile phone.

Thank you for your help, it seems hard to solve this problem because there is no device use the same port Goip linked directly to the router and the provider forwarded the IP to local port with port 5060, 5061 and 5090

I dont know why they use 5090

Dst. Address: my public IP
Dst. Port: 5060

To Addresses: server IP
To Ports: 5090

You say your provider is forwarding ports. Is your router not assigned a public IP by your ISP?

If not then there may be a double NAT, where your provider avoids using public IPs, by assigning your router a private one. This is going to introduce the possibilities of even more issues, if true.

And I'm not certain where port 5090 comes into play.

It's assigned to the router also i can login to it outside the network I use the same IP from 3 months, also I pay extra for this IP

About the 5090 I think they do it by mistake! I will change it to 5060
