Specific Features

Enabling Alternate Ringtones Alternate ringtones can be supported by sending additional information in the SIP Headers When SIP Server generates a new call via an INVITE, it can add the Alert-Info header, endpoints can then interpret this for custom ringtones The option sip-alert-info details the ringtone or ringtone location for the endpoint to play. Similar options sip-alert-external and sip-alert-consult apply specifically to external or consult calls 2012, Genesys Telecommunications Laboratories All Rights Reserved 37

Media Server Reliability MSML SIP Server supports the SIP SUBSCRIBE/NOTIFY method for providing reliable MSML-based media services through Genesys Media Server. By subscribing to the DN used to represent Genesys Media Server for msml-based services, SIP Server is able to determine when a particular instance of Media Server becomes unavailable, and if so, SIP Server can disconnect from the failed media server, then reconnect to an available instance of Media Server, providing continuity for any ongoing msml-based media services. 1. SIP Server sends periodic SUBSCRIBE messages to GVP Resource Manager for each Voice over IP Service DN (service-type is set to msml ) that SIP Server is subscribed to. 2. If a particular instance of Media Server becomes unavailable, Resource Manager sends a NOTIFY message to SIP Server, which lists the status of each media server monitored by Resource Manager. A sample body for the NOTIFY message is as follows: *msml/<mediaserver-ipaddress>:<mediaserver-port>/out-of-service* 3. SIP Server disconnects all ongoing media services from this Media Server instance, then reconnects with an active Media Server through Resource Manager. 4. All existing treatments and conference connections are re-established on the alternate Media Server instance. 2012, Genesys Telecommunications Laboratories All Rights Reserved 38

SIP Server - GVP Media Server (Call recording) SIP Server 8.1.0 is now integrated with Genesys Media Server 8.1.4 and 3 rd 39 party recorders. Integration is done by MSML protocol.

Call Delivery - DR-pair Target detection & Forwarding The Party that originates the direct inbound (or internal call) call does not know the current agent s location. So call can arrive to any server in a DR pair. Target Detection & Forwarding procedure takes measures to deliver the call to the proper site in Business Continuity deployment. - The procedure is applied to all calls to be delivered to the agent DNs. - If destination is ready for call, call is delivered to it. Otherwise, call is forwarded to the DR-peer. - This activity related to agent availability only. There is no intention to try the second site destination if phone is inaccessible on the first site. - To avoid the infinitive loop of forwarding procedures in case of logged out agent, the forward SIP messaging includes private URI parameter in the Contact (for 302) or Refer-To (for REFER ). Contact: <sip:7101@dr-peer:5060;x-genesys-dr-forward> - So, if call has been already forwarded from peer site then current SIP Server must try to deliver it to DN requested independently of agent status. 2012, Genesys Telecommunications Laboratories All Rights Reserved 83

Failure detection Sip Server - Utilizes the dedicated trunk which points to its peer. - Trunk name is defined in application option dr-peer-trunk. - The Out of Service check mechanism configured on this trunk provides the failure detection functionality( options oos-check and oos force. Desktop (T-Lib client) - Desktop must use the ADDP protocol to detect site availability. SIP end point -failure detection depends on the phone model - Bria: Supports Send SIP keep-alive option. End point utilizes empty messages sent to SIP port and relies on ICMP errors to detect - Polycom SoundPoint: it does not have keep alive mechanism. The failure could be detected by failing of outbound call or renewal of the registration. - ALU 40xx uses OPTION request to check the SIP Server availability. Important that it does not continue sending OPTIONS to a dead site. So, it cannot detect the primary peer recovering. As result, it continues to work with secondary peer until failover on secondary site. 2012, Genesys Telecommunications Laboratories All Rights Reserved 84

Graceful migration BC supports graceful migration of operations from two active/active SIP Server Peer sites to a single site Graceful migration includes administrative and automatic parts: 1. Configure your MGW to stop sending calls to the SIP Server Peer site that you intend to shutdown. 2. Possible step is starting the dedicated strategies on URS. 3. Using Genesys Administrator, then initiate a graceful shutdown of the SIP Server During the graceful shutdown procedure SIP Server 1. Moves all agents into NotReady state 2. Logs out all agents who does not have active calls (with appropriate reason code ) and declares DN Out of Service 3. Rejects all INVITE with configurable final response (option shutdown-sip-reject-code ) 4. Forbids any call created T-Request. 5. Rejects all agent login or ready requests. SIP Server waits until last call is finished and then stops. 2012, Genesys Telecommunications Laboratories All Rights Reserved 85
