[sercangoger]

I have a domain. it is this way too. www.mydomain.com for me to communicate with TLS; www.sip.domanim.com or www.sips.domanim.com

Do I need to create a domain like.

is this a requirement?

I have a similar issue. I had a domain like www.mydomain.net. And even though I made all the settings for FlexiSIP, I could not run TLS successfully. I created a subdomain like example.mydomain.net. still no results.

Does it really need to be sip.mydomain.net or sips.mydomain.net?
