| Question ID 12924 | Refer to the exhibit.
During a QSIG tunneling over SIP call establishment, which two types of SIP messages
can the OGW use to tunnel a waiting QSIG message? (Choose two.)
|
| Option A | SIP re-INVITE
|
| Option B | SIP NOTIFY
|
| Option C | SIP INFO
|
| Option D | SIP OPTIONS
|
| Option E | SIP UPDATE
|
| Option F | SIP REFER
|
| Correct Answer | A,E |
Explanation Explanation: The TGW sends and the OGW receives a 200 OK response--the OGW sends an ACK message to the TGW and all successive messages during the session are encapsulated into the body of SIP INFO request messages. There are two exceptions: When a SIP connection requires an extended handshake process, renegotiation, or an update, the gateway may encapsulate a waiting QSIG message into a SIP re-INVITE or SIP UPDATE message during QSIG call establishment. When the session is terminated, gateways send a SIP BYE message. If the session is terminated by notice of a QSIG RELEASE COMPLETE message, that message can be encapsulated into the SIP BYE message.
