Please check your Freepbx account. When you make a call through the route you defined, Freepbx returns 403 response.

Best regards,

Posts: 13 		I found the FROM SIP header to be incorrect in my SIP application.
We have fixed that now, and will test again.
Thank you.

Still not working, here is what we have done.
1. We tested our SIP app with another proxy server, and it works fine.
2. Your TekSIP requires both endpoints. So we added the VoIP provider in the route and endpoint. We do not see TekSIP registering with the VoIP provider in the logs.
3. We added our SIP app to the endpoint and registered it. We can see that our SIP app has registered.

4. We placed a SIP call which is directed at TekSIP IP address. It does not work, log files included.

5. Our SIP app has already been tested and confirmed working with the same VoIP provider that we are using with
TekSIP.

Log files are below:

Is it possible you to send me a sample session (Wireshark trace maybe) for your application to the same provider?

Thank you for looking into this.

This sharkwire trace (attached) shows a call made by our SIP app to the same VoIP provider through out Intertex SIP aware firewall.

Thank you,

Michael

FreePBX works fine with our SIP app.
As we mentioned before, we have tested our SIP app with a SIP Proxy and FreePBX, and it works fine.
We have tested our SIP app, with a SIP aware firewall and FreePBX and it works fine.
Only when we use your SIP proxy does it not work
The reason we want to use your SIP proxy, is you have a free trial (same as we do), and
this will allow our perspective clients to test our system (and yours) before buying. Most of our
clients do not have SIP aware routers and are behind a NAT.
Let us know if this is something you want to keep working on. I think it would
be advantages for both companies to resolve this issue.
Thank you,
Michael

Still not working, make sure when you test you place a call through the VoIP provider, get connected and have two voice paths.
Thanks,
Michael

Posts: 13 		Also lets use the same test bed, what SIP app are you ubsing to place calls through your Proxy to the VoIP provider.

Also lest confirm we are setting up TekSIP the exact same way. Please can you list a step by step process when setting up TekSIP, when using a SIP app to call
through to a VoIP provider, behind NAT.

Thank you,
Michael

Posts: 254 		Hi,

Please see attached Wireshark and TekSIP.log. TekSIP and Softphone software (X-Lite) are installed on the same machine.
TekSIP is behind a NAT gateway which supports UPnP. TekSIP detects external IP address at startup and provides NAT traversal.
If your NAT gateway does not support UPnP you can specify external IP address manually at Settings / Service parameters.

Best regards,

Yasin KAPLAN
