How this service works
Call when an agent needs SRV records at _h323._tcp.{hostname} for H.323. The caller sends the registrable domain, not the underscored name. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-h323 first.
Output
Returns the SRV record set found at _h323._tcp.{hostname}, including priority, weight, port, and target hostname for each record, enabling H.323 service discovery.
Example use cases
H.323 gatekeeper discovery for enterprise
“Can you look up the H.323 SRV DNS records for acme-corp.com? I need to find their H.323 gatekeeper host and port for a video conferencing integration.”
VoIP infrastructure audit
“Check whether polycom-partner.net has any _h323._tcp SRV records configured — I'm auditing their VoIP setup and need to know if H.323 service discovery is in DNS.”
Troubleshoot H.323 connection failure
“I'm having trouble connecting to the H.323 system at university.edu — can you pull the SRV records for _h323._tcp on that domain to see what host and port they're advertising?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-h323?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover H.323 VoIP/video conferencing endpoints via DNS SRV records for a given domain. It handles the _h323._tcp prefix internally so callers only need to supply the plain registrable domain. Prefer the free sandbox endpoint /v1/sandbox/dns-srv-h323 first; use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- Domain does not have _h323._tcp SRV records — returns empty or NXDOMAIN response
- Invalid or malformed hostname input — request rejected
- Hostname exceeds 253 characters — validation error
- DNS resolution timeout or upstream resolver failure
- Private or reserved domain names may not resolve
