Re: [asterisk-users] RS485 Audio device

Before walking down this path, take a moment to think critically: How far away is the AoR from the attendant station? Does there need to be local rescue/fire service access to the communications? How reliable does the link need to be? Will power always be available when the AoR pone is required

[asterisk-users] AMI Originate and 183 response

I to Originate channels using AMI. When the other end indicates the channel is ringing, I need to do some system notification work. Everything works great when the ITSP sends a 180 Ringing response. Through AMI events I see the channel state changed and can do the necessary work. However,

Re: [asterisk-users] RS485 Audio device

If cable can be pulled , you have a couple of options. Long Reach Ethernet from Cisco is rated for 5,000 feet. Multi-mode fiber with fiber/ethernet media converters on each end would work and electrically isolate the two ends of the cable. Both are way overkill from a capacity standpoint, but

Re: [asterisk-users] RS485 Audio device

Forget RS485 at that distance (your throughput will be too low). I would suggest you pull a fiber and just create an LAN connection on the end. I’m sure you would have had fun getting some of the old IP over Serial drivers working J From: asterisk-users-boun...@lists.digium.com

Re: [asterisk-users] RS485 Audio device

Unless there is already RS485 in place, forcing the use of that type of bus, this sounds to me like something that would be more easily achieved using one of those 2-wire SIP doorphones that puts standard analog audio over a copper pair between the handset and the base. I don't have any

Re: [asterisk-users] RS485 Audio device

Hi All, The reason for the question was simply that the customer desired some solution called an "AOR" or Area of refuge - I think it was. Basically a call button, microphone and speaker to hear back with the kicker being "a long distance" the solution has to run. RS485 is like 4000 feet. There

Re: [asterisk-users] RS485 Audio device

It caught my interest for the same reason! It's such an obscure query. My guess was that the desire was to run it over an existing shared RS485 bus, which means the maximum data rate available would be even less because it would be shared with other devices. The only way I could imagine a

Re: [asterisk-users] RS485 Audio device

This one caught my interest too...more out of curiosity! Keep in mind that RS485 max speed drops to 100kbps after a relatively short distance. And, 100kbps is RAW speed. If you encapsulated your audio stream in that you'd lose another 10%. So why are you doing this? If you are running a 100m

Re: [asterisk-users] RS485 Audio device

Why RS485? Whats wrong with a simple 3-wire connection (monospeaker, monomic, ground) where you short monomic to ground on button press? Then you could use a simple usb device + device server to convert fron "smartphone headset" to usb then to network. On the server, you use a SIP phone

Re: [asterisk-users] Realtime queue & agent groups

Hello any one have some input on this ? I've already tried changing the membername to : testacc77000/@1 Is completely ignored. I've already tried changing the interface to : testacc77000/@1 Is completely ignored. Or is it just not possible to group queue members ?? Thanks. J. On
