How about Intercom? From what I remember (and read below) it's a feature which automatically connects the caller to the recipient in whisper mode so that the called party hears everything but can't actually talk back until they initiate so. No ringing, auto-answer. I'm not sure if there is a one-to-one or one-to-many relationship and how that would work at the end unit. But that being said, that would be a problem with any solution. Multiple locations sending panic calls to one destination (campus police).
If it were me, I'd investigate intercoms. http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmfeat/CUCM_BK_F3AC1C0F_00_cucm-features-services-guide-100/CUCM_BK_F3AC1C0F_00_cucm-features-services-guide-100_chapter_0100011.html [http://www.cisco.com/web/fw/i/logo-open-graph.gif]<http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmfeat/CUCM_BK_F3AC1C0F_00_cucm-features-services-guide-100/CUCM_BK_F3AC1C0F_00_cucm-features-services-guide-100_chapter_0100011.html> Features and Services Guide for Cisco Unified ...<http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmfeat/CUCM_BK_F3AC1C0F_00_cucm-features-services-guide-100/CUCM_BK_F3AC1C0F_00_cucm-features-services-guide-100_chapter_0100011.html> www.cisco.com Features and Services Guide for Cisco Unified Communications Manager, Release 10.0(1) -Intercom --- Lelio Fulgenzi, B.A. Senior Analyst, Network Infrastructure Computing and Communications Services (CCS) University of Guelph 519-824-4120 Ext 56354 [email protected] www.uoguelph.ca/ccs Room 037, Animal Science and Nutrition Building Guelph, Ontario, N1G 2W1 ________________________________ From: cisco-voip <[email protected]> on behalf of Lisa Notarianni <[email protected]> Sent: Monday, January 30, 2017 4:18 PM To: [email protected] Subject: [cisco-voip] Panic Button Solution? Call Manager 10.5.2.12901-1 I have a request from a department here at The University of Scranton to use a button on their phone as a panic button that would do the following: 1. Automatically dial our Police department without a ring tone 2. Provide one way communication to University Police so they can listen to the conversation to get an idea of the issue and then dispatch an officer It is important to have silence on the phone connection when the button is pressed I looked into PLAR but I don't think it can be configured exactly this way. We have a SingleWire server but it is in the process of being upgraded. So, before we install a physical panic button without a voice feature, we wondered if there were any other creative solutions. Thank you in advance - Lisa Notarianni [Lisa Notarianni Telecom Engineer]
