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 to function? I did a 27mA powered intercom system at a chemical plant a bit over decade ago, the old analog circuits are dead simple - just a battery (or a double battery-backed power supply in my case), a current regulator and an audio bypass cap to make a simple audio loop. If that's too much hardware, there are still sound-powered phones produced - very common in mining and maritime. An SIP phone can be wired into a sound powered phone circuit, where the preferred usage would be talking via SIP phone, but if all powered failed the sound-powered devices on the line would still make a complete audio circuit.

[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, when the ITSP sends a 183 with SDP response, there is no notification through AMI indicating anything has changed. Until the channel is answered, rejected, other failure, or ITSP sends 180 Ringing I do not see any updates via AMI events. I realize the 183 Progress is not a Channel State change so AMI cannot send an AMI event indicating any channel state change. Is there some way to know through AMI whether a 183 has been received?

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 sometimes there's nothing wrong with overkill. Put an ATA on the far side.

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.

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 specific model to reference to, but they've definitely been discussed on-list before.

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 solution working in this scenario would be some sort of ATA attached to a router which supported PPP and had an RS232 serial port on the WAN side (eg like an old modem router), which could then be converted into RS485. You could possibly do all that in a Raspberry Pi with a USB-RS232 adapter (or even a USB-RS485 adapter directly!). Then you'd run SIP over IP over PPP to a similar device on the other end of the bus. But you'd obviously have to be sure to use a low bandwidth codec, and you'd possibly suffer audio quality issues when there was (RS485) bus contention. But that was all guess work. It would be great if OP Jerry could expand a little more on the application scenario, even if just to whet the curious appetites :) Pete > On 3/11/2016, at 3:48 am, Telium Technical Support wrote: > > This one caught my interest too...more out of curiosity!

For most modules there isn't a big point to disabling them as there isn't an lot of ongoing CPU activity for a module not being used. That being said, there are some things you can disable that can improve your performance, but they're going to be application dependent. I believe that disabling CDRs, for example, can make a big difference on heavily loaded systems and some people don't use them. CDRs take some amount of work at the end to stitch together the notion of a call from the various call related events that occur. HEP also is a big offender. CELs and AMI can also make some difference when disabled, but nothing on the order of CDRs and HEP.

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 cable (4 wire + shield) why not just pull at cat5/6 cable instead? Or just send analog audio over 2 of the wires with the shield to keep out hum. If there is a need to use rs485 you could stream your audio over that connection - but I'm curious why first. We did some work for broadcast (radio station) doing AoIP and converting some analog feeds but this seems unusual.

Ok, I'll bite. How does one do audio over RS485? I've never worked with RS485, but from some brief googling it looks like it's a fancy version of RS232.

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 client, who use this device as mic/speaker, which is configured to lift the hook on headset button press. In asterisk dialplan, you have logic which automatically dials where the doorphone should call upon hooklift. smime.p7s Description: S/MIME Cryptographic Signature -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
