Hi, I'm new to this forum and Centrex proxy.

We are placing the proxy between a Yealink T26 phone and
a 3CX PBX.

When Yealink is configured to a 3CX listening on port
5060 it does not add the port number into the REGISTER
Request-Line. The registration fails as proxy does not
forward the REGISTER to the 3CX.

==================================================

When Yealink is configured to a 3CX listening on another
port (say 6500) it does add the port number into the
REGISTER Request-Line. The registration is fine as the
REGISTER is forwarded correctly to the 3CX.

I have posted 2 PDFs with some environmental info and
screenshots to the insperix FTP area on your FTP servers.

Do I have a config error somewhere?

Hi Tom,

Everything in the SIP looks normal from what I see.

If you have your LanScape SIP proxy using port 5060, change that to another port and see if registrations from the phones using port 5060 are then forwarded to the 3CX pbx. I would have to look into the code and run fake REGISTER scenarios based on your SIP to see why this may be occurring.

When we spoke on the phone, I mentioned that SIP interoperability issues could arise. If there are SIP interoperability issues, we can eventually address them in order to get all the REGISTER and call flow scenarios working as we like.

For now, get as much of your deployed scenario working as possible. We can keep track of any issues that we may eventually want to address.

Free support:
I am sure you already know this…
Please note that free support is limited. Free support is for helping customers with simple questions regarding our software products and for basic configuration issues. Only with paid support do we get involved with investigating SIP interoperability issues. Customers who do not require paid support handle all their own issues as required.

Thanks,

RJ
