I've got 2 Nortel's at 2 different PSAPs (Public Safety Answering Points--911 centers). Both have Dictaphone recording equipment.
The first one was installed about 2 years ago. They record 8 digital phones (about 15 digitals for the PD total) and 8 analog inputs; radios and such. Dictaphone actually has a board that bridges with the digital extensions and decodes the audio. The boards catch the on-hook,off-hook, and hold data and start and stop recording appropriately. No false recording due to audio levels or anything. That site is combined with the rest of the City Hall, for a total of about 45 sets. They use a PRI for trunking with a few POTS backup lines. The second site is also Dictaphone, about 120 sets. It was installed earlier this year. However, they didn't ask me what to use, so instead of the Nortel interface card, whoever the Dictaphone rep was installed those little handset bridges that require a pair back to the recording unit. They seem to be quite troublesome. On both systems, they have access to a PC running Dictaphone's software so they can play back any recordings from any channel at any time. It uses DVD-RWs to store and archive the audio files. ----- Original Message ----- From: "Charles P." <[EMAIL PROTECTED]> To: "Dave Phelps" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Tuesday, July 16, 2002 8:09 PM Subject: Re: Re: Re: Re: Recording Multi Lines | | | > | > I don't agree.

A lot probably depends | on | > the size of the PD. | | Cost wise, recording the trunks should be far less than dedicating a record | channel to each extension. Identifying who placed or received the call is | usually less important than the content. You could correlate the smdr with | the recordings if you needed to id extensions or operators. It would make | sense for one of the recorder manufacturers to be able to connect the smdr | to the recorder so the call data could be displayed with the voice data. | They might already do this on some of the pc based recorders (wishful | thinking)? | | They may want the ability to have instant replay at an operator's desk - | this could be done with a unit dedicated for that purpose. I've seen units | made with a certain number of minutes being digitally recorded, and the most | recent activity available for instant playback. If it was a 911 call center | they would probably want something different all together. | | | Thinking out loud, | Charles | | | | | | | _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
