How many SRV records would need to be created when both SIP and H.323 are being used?

Explanation

When both SIP and H.323 protocols are deployed, five SRV records are required. SIP requires three records: _sip._tcp, _sip._udp, and _sips._tcp (for TLS). H.323 requires two records: _h323cs._tcp (Call Signaling) and _h323ls._udp (Location Services/Gatekeeper discovery). Combined, that totals five SRV records (3 SIP + 2 H.323 = 5).
