Which two SRV records are valid for a SIP and H.323 communication? (Choose two.)
Correct Answer: A,C
The format of DNS SRV queries for sip (RFC 3263) and H.323 used by Expressway are:
_sips._tcp.<fully.qualified.domain>
_sip._tcp.<fully.qualified.domain>
_sip._udp.<fully.qualified.domain> - not recommended for video calls, only use for audio-only calls
_h323ls._udp.<fully.qualified.domain> - for UDP location (RAS) signaling, such as LRQ
_h323cs._tcp.<fully.qualified.domain> - for H.323 call signaling
The format of DNS SRV queries for sip (RFC 3263) and H.323 typically used by an endpoint are:
_sips._tcp.<fully.qualified.domain>
_sip._tcp.<fully.qualified.domain>
_sip._udp.<fully.qualified.domain> - not recommended for video calls, only use for audio-only calls
_h323ls._udp.<fully.qualified.domain> - for UDP location (RAS) signaling, such as LRQ
_h323cs._tcp.<fully.qualified.domain> - for H.323 call signaling
_h323rs._udp.<fully.qualified.domain> - for H.323 registrations
_sips._tcp.<fully.qualified.domain>
_sip._tcp.<fully.qualified.domain>
_sip._udp.<fully.qualified.domain> - not recommended for video calls, only use for audio-only calls
_h323ls._udp.<fully.qualified.domain> - for UDP location (RAS) signaling, such as LRQ
_h323cs._tcp.<fully.qualified.domain> - for H.323 call signaling
The format of DNS SRV queries for sip (RFC 3263) and H.323 typically used by an endpoint are:
