Thank you, Neal Haas Neal Haas IT Analyst Please report Troubles to the Help Desk. 559-600-5900 Telephone (559) 600-5890 FAX (559) 455-4747 County of Fresno Information Technology Services Division 2048 N Fine Ave Fresno, CA 93727 From: cisco-voip [mailto:cisco-voip-boun...@puck.nether.net] On Behalf Of Thomas Theisen Sent: Monday, June 27, 2016 7:31 AM To: cisco-voip@puck.nether.net Subject: [cisco-voip] Trouble Getting 8831 to register I have been working with TAC trying to get our first 8831 phone to register with our 10.0.1.11900-2 CUCM but we have had no success. The strange thing is that I found that the registration is "Rejected" before I even patch the phone into the network. TAC updated the load information for the 8831 to sip8831.9-3-3-TO-10-3-1 so I think I have the most up-to-date load for the phone. I am using a switch port that had a 7965 attached to it so I know the pathway to CUCM is clear. This is the first sip phone we have tried to introduce to the system but we have sip trunks so I know the correct ports are enabled for sip. -- Thomas Theisen Network Tech IV University of Rhode Island 401-874-7870
