Call Queuing Interactions Interaction Feature If a call is routed to a queuing-enabled hunt pilot through SIP ICT, the SIP ICT uses the SIP profile that has SIP Rel1XX Options set to Send PRACK if 1XX contains SDP. As a result, the initial announcement is played to every call before the call is extended to the line member. The above existing interaction for SIP ICT does not apply if Connect Inbound Call before Playing Queuing Announcement checkbox is checked under DeviceDevice Settings SIP Profile > Trunk Specific Configuration in Cisco Unified CM Administration. If Connect Inbound Call before Playing Queuing Announcement checkbox is not checked the interaction for SIP ICT remains the same. However, it does not guarantee the initial announcement can always be heard by a caller from the PSTN side. The initial announcement will not be heard by a caller from the PSTN side if the PSTN provider doesn't open the voice path until a Connect message is received on the call. SIP Rel1XX Options • The logoff notification functionality for hunt groups changes when Call Queuing is enabled for a hunt pilot. If Call Queuing is enabled for a hunt pilot, the Hunt Group Logoff Notification does not play when users log out of a hunt group or are logged off because they missed their turn in the queue. • If the hunt list has multiple line groups, these line groups must have the same setting for Automatically Logout Hunt Member on No Answer. • Hunt Pilot still queues calls, even when all hunt members are logged out.The line group members should not be added in more than one line group and even if they are added in second line groups, those second line groups should not be in the same Hunt list. • All hunt options must be set to Try Next Member, then Try Next Group in the hunt list.
