We have found using the intercom with the headset connected to analog paging systems tends to work the best. There is hardware that will do this, however the expense and lack of "features" (analog line equivalent vs voip phone) seems to point us back to the phone. We have used both Sipura and InnoMedias for other analog connections. Our default: We often use the Aastra 6753i mounted to the wall in the dmark and punched down to the 66 block from the headset port. We often do not have a handset connected either (could be useful to have one for 911 calls from that location if needed). We primarily use Aastra phones which is why we chose the model we did. It has a webpage for local/manual config changes (customers controlling their system) and pulls an update from our config servers nightly if we need to make changes. The buttons/display can be locked or unlocked remotely from the webpage as well (it has an emergency dial plan for when it is locked as well).

The site is about a thousand miles away so I can't just go play with it. At the most basic level I'm considering just a cheap phone on auto-answer and a connection from its headset jack to the paging amp. Any other ideas? -- Carlos Alvarez TelEvolve 602-889-3003 _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops

Hahaha, now that would be funny. <BLARING SPEAKER>YOUR AUTO WARRANTY MAY BE EXPIRING...... I've just learned that this paging amp has an RJ11 input, so a simple ATA on auto-answer should be fine. -- Carlos Alvarez TelEvolve 602-889-3003

If you've got enough speed dials and the right gear, you can use non-dialable DTMF digits (A-D) to hide this kind of thing from autoattendants, etc. David From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Brian R Sent: Tuesday, March 13, 2012 10:15 To: voiceops Subject: Re: [VoiceOps] Paging system integration with VoIP This has happened to one of our customers. They liked the idea of being able have management call in in an emergency to use the system. They have now decided to us an off the wall extension to do this from the main attendant (normal extensions 3xx and paging extension 8472 for example).
