CUCM Line Group 2 Not Ringing Phone

[zdesignstudio]

Good morning,

I have encountered a weird issue and was wonder if anyone here could provide some insight before I send it up to TAC.

I have a Hunt Pilot (HP)/ Hunt List (HL) and the HL has 3 Line Groups (LG) associated to it. Example LG configuration is below.

LG1: 1001, 1002, 1003

LG2: 1001, 1002, 1003, 1004

LG3: 1001, 1002, 1003, 1004, 1005

All LGs are set to RNA of 15s and broadcast.

Call comes in and hits LG1. 1001, and 1002 are on the phone so they do not receive a notification and 1003 just doesn't answer call even though 1003 is the only one ringing. Call rolls to LG2 and 1001, and 1002 are still on phone, but 1003 and 1004 don't answer even though those two phones are only ringing. Before the call rolls to LG3, 1001 hangs up the phone. Now when the call rolls to LG3, 1001 doesn't ring. The only phones that ring are now 1003, 1004, and 1005. 1002 is still on the phone from the beginning and this is expected of course but why doesn't 1001 ring even though the phone is on hook and was put on hook before the call went to LG3?

Phone Types: 6921, 7821, 7942, 7962

Phone FW: 6921 - SCCP 9.4.1.3, 7942 - SCCP 9.3.1ES13, 7962 - SCCP 9.3.1ES13, 7821 - 10.1.1ES6

CM Version: 9.1.2.10000-28

Thanks,
