Sip Trunk over TLS not working

[claudiotele]

I programmed a Sip Trunk with TLS but it does not register with the IPO500v2, but with Microsip Softphone it registers.
Can someone help me?

Those are not that many information. I would start with the correct CA certificates.

 

[claudiotele]

I used the certificates sent by the operator, but Microsip does not use a certificate and it works.

Again, a total lack of any useful information. We don't have access to your system so we can only work with what you tell us.

How was the system and trunk configured? What appears in system monitor went you attempt to make calls in/out? How is the SBC configured?

The settings for connection of a SIP trunk are entirely separate from those for the connection of SIP softphones. So it's very easy to have one work whilst the other doesn't.

Maybe Microsip is forgiving if a certificate is not valid. IPO isn’t.

 

[claudiotele]

these are the settings















monitor

No response… probably a certificate issue or a blocking firewall. The second last line looks like a certificate problem.

this is a certifcate issue. upload the provider certificate to the IPO 500 v2 or download the certificate of the IPO and upload it on the provider side.
