How this service works
SIPFEDERATIONTLS service discovery (_sipfederationtls._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's sipfederationtls service lives without guessing hosts. $0.01 per lookup.
Output
Returns SRV record data for the _sipfederationtls._tcp service under the queried domain, including one or more records each containing priority, weight, port number, and target hostname — enabling a client to connect to the correct SIP federation TLS endpoint without guessing.
Example use cases
Verify Microsoft Teams SIP federation setup
“I need to check if fabrikam.com has its SIP federation TLS DNS records configured correctly — can you pull the _sipfederationtls._tcp SRV records and show me the target host, port, priority, and weight?”
Diagnose SIP federation connectivity issue
“We're having trouble federating with acme.com over SIP TLS. Can you look up their _sipfederationtls._tcp SRV record so I can see what host and port their system is advertising?”
Audit domain SIP federation configuration
“I'm auditing our partner domains for unified communications readiness. What do the _sipfederationtls._tcp SRV records look like for northwindtraders.com?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/sipfederationtls-tcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover the SIP federation TLS service endpoint for a domain — especially for Microsoft Teams, Skype for Business, or other SIP-based unified communications platforms that publish _sipfederationtls._tcp SRV records. Prefer this over manual DNS tools when automating federation setup verification, partner domain audits, or connectivity diagnostics.
Side effects
- Domain has no _sipfederationtls._tcp SRV record configured — returns empty or NXDOMAIN result
- Invalid or malformed domain name input — returns error
- Cloudflare DoH upstream timeout or failure — returns service error
- Domain exists but SRV record set is empty — returns no results
