SRV records doubt

Hi, I have those two SRV records:

_sip.domain.ch SRV 3600 100 1 443 sipdir.online.lync.com
_sipfederationtls.domain.ch SRV 3600 100 1 5061 sipfed.online.lync.com

which I added to CloudFlare, the problem is that in CloudFlare I need to select a protocol: TLS, TCP, UDP… and the same is appended to the DNS records, which become:

_sip._tls.domain.ch SRV 3600 100 1 443 sipdir.online.lync.com
_sipfederationtls._tcp.domain.ch SRV 3600 100 1 5061 sipfed.online.lync.com

Would this cause issues or is it supposed to work like that?

That’s not unique to Cloudflare. That’s a DNS standard for SRV records.

There are many other threads here about SRV records for SIP with examples of what records look like:
https://community.cloudflare.com/search?q=_sip

But those SRV records on the current hosting are defined without protocol in the domain name:
_sip.domain.ch SRV 3600 100 1 443 sipdir.online.lync.com
_sipfederationtls.domain.ch SRV 3600 100 1 5061 sipfed.online.lync.com

I’m not sure if migrating NS records to Cloudflare and not having records exactly as they’re defined on the current hosting will broke something or not.

I should have researched the topic a bit before. I found this article here:

My records should work as expected even with the protocol defined in the hostname.
