QuestionQ48

Protocols and Endpoints

Which two protocols are proxied through an Expressway-E/C pair when an MRA login that includes phone services is performed?

Choose two
  • A SCCP
  • B HTTPS
  • C H.323
  • D SRTP
  • E SIP
Explanation

MRA proxies HTTPS for client logon, provisioning, and configuration services, and SIP for session establishment and registration. Phone services therefore require SIP signaling in addition to HTTPS client-service traffic; SRTP is used for media rather than login or registration.
