Why is the initial REGISTER request from a SIP endpoint rejected by Avaya Aura® Session Manager (SM)?

The initial REGISTER request is rejected only if the user provided the wrong security code/password.

The intital REGISTER request does not contain authentication details.

The initial REGISTER request is rejected only if the user provided the wrong security code/password.

It must confirm the reliable delivery of this initial REGISTER request.

System Manager needs time to look-up the Communication Address in its database.

Which three statements about media processing resources (DSPs) are true?(Choose three.)

If a direct media path cannot be established between two IP endpoints the call will fail from release 7.0.

Two-party calls originated by H.323 stations, trunks, or media gateways, and terminated by SIP stations or trunks, cannot shuffle.

SIP-SIP two-party calls will always use SIP Direct Media if Communication Manager (CM) is configured to do so.

If a direct media path cannot be established between two IP endpoints the call will fail from release 7.0.

Two-party calls originated by SIP stations or trunks, and terminated by H.323 trunks, media gateways, or other vendors’ H.323 stations, will typically shuffle if Communications Manager (CM) is configured to do so.

H.323-H.323 two-party calls will always shuffle to establish a direct media path if Communications Manager (CM) is configured to do so.

Two-party calls originated by H.323 stations, trunks, or media gateways, and terminated by SIP stations or trunks, cannot shuffle.

SIP-SIP two-party calls will always use SIP Direct Media if Communication Manager (CM) is configured to do so.

When a 96xx telephone with SIP firmware boots up, it goes through a number of steps.These steps include:

Phone Registration 2.Download PPM.

Obtain IP Address and http/https server address from DHCP Server.

An IP (AST) user 1011111 and H.323 User 1011711 share a common Communication Manager (Evolution) server. Given the following actions:

CM will negotiate the codec for the H.323 endpoint based on CM configuration.

Session Manager verifies SIP user 1011111 in the registry and authenticates it. After authenticating the SIP user, Session Manager checks the SIP user’s profile for sequenced applications and routes the request to CommunicationManager.

Communication Manager performs feature processing and terminates the call to the H.323 endpoint. 4. SIP user 1011111 dials H.323 Ext. 1011711 and an INVITE request is sent to Session Manager.If SIP user 1011111 calls H.323 use 1011711, in which order will these actions take place?

4, 2, 1, 3 B.4, 3, 2, 1 C. 4,2, 3, 1

Refer to the exhibit. A SIP user is calling an H.323 user.In this call flow, during which phase does the Avaya Communication Manager (CM) Evolution Server handle the processing for each endpoint?

SIP endpoint in originating phase, H.323 endpoint in terminating phase

H.323 endpoint in originating phase, SIP endpoint in terminating phase

SIP endpoint in originating phase, H.323 endpoint in terminating phase

both endpoints in the terminating phase

both endpoints in the originating phase

SIP user 1011111 is trying to callSIP user 1021111.If Session Manager cannot find a matching SIP Communication Profile for 1021111 in its SIP registry, what happens next?

Network Routing Policy (NRP) is consulted for further routing instructions.

The Call is sent to Communication Manager to check if the number dialed exists in CM’s call routing tables.

The Caller receives a busy tone.

Network Routing Policy (NRP) is consulted for further routing instructions.

The call is routed to voicemail to check if the extension is associated to a mailbox.

SIP (AST) user 1011111 and SIP (AST) user 1011112 are both based on the same Session Manager with access to a CM Evolution server. Given the following actions:

SIP user 1011111 calls SIP user 1011112 and an Invite request is sent to Session Manager.

Session Manager searches for the called party in the SIP registry, finds it, registers it and routes the call to it.

SIP user 1011111 calls SIP user 1011112 and an Invite request is sent to Session Manager.

Session Manager verifies SIP user 1011111 in the SIP registry and authenticates it. Session Manager checks the SIP user’s profile for sequenced applications and (in this example) routes the request to Communication Manager.

Endpoints negotiate codecs and media and RTP is sent between endpoints.

Communication Manager receives the request from Session Manager, carries out full-call model processing for both endpoints and routes the call back to Session Manager.If 1011111 makes a call to 1011112, in which order will the actions take place?

Which statement about H.323 endpoint to SIP Avaya SIP Telephone (AST) endpoint routing is true?

Avaya Aura® Communication Manager does feature processing for both endpoints.

Avaya Aura® Communication Manager does feature processing for H.323 endpoint only.

Avaya Aura® Communication Manager does feature processing for SIP endpoint only.

Avaya Aura® Communication Manager does not do feature processing for any endpoint in this scenario.Answer: A
