Algo8301 multicast zone paging demo

- Half-assed demo of Algo8301 multiple zone extensions transmitting to 4 different multicast paging zones. Scanner audio feeds what Algo calls the "music" zone, which has the lowest priority. Calling the different extensions configured in the Algo8301 page to a different group of speakers with each demo call shown.
The audio is terrible, but it's the thought that counts.
Nice!
Is this comperable to a Snom PA1?
What model scanner is that ? I am looking to setup a similar event in lab just to mess with and better learn VOIP.
I acquired a brand new 8301 for about $150(Great deal) and a few 8180 G2's instead of the bull horns.
Can you use Valcom Ip POE speakers instead of Algo brand?
I don't know for sure. The thing that makes these Algo speakers do this is their use of IGMP multicast groups to distribute audio. AFAIK there is no additional signaling riding on the RTP multicast stream, so if the Valcoms work similarly then you could probably set them up this way.
I just got tired of Valcom's ancient approach with their programming app that does this weird reverse ftp of settings down to your Windows (and it MUST be a Windows) computer, edit settings, then hit Submit so it would ftp the settings back to the Valcom device; no web nor command line interface. My calender reads 2023 so they need to get with the current century. Outside of that, Valcoms work well.
Algo stuff has a web interface for easy changes to the settings, as well as provisioning files if you want to control settings that way. Much better system.
@@boteman3428 thank you for your direction. I ended up using Algo8301 for scheduling/tone generator and 3 Valcom speakers (2 horns, 1 ip clock/spkr) for the final setup.... took some back/forth with all firms and tech support at Valcom ended up helping me solve the issue.....all working fine now.
I totally see your frustration with antiquated method of programming/updating Valcom vs Algo's internet-based menus....wow, so much easier!
I must say the volume from Valcom speakers is amazingly loud (due to internal amps?).......perhaps a compromise as I feel i have the loudest sound needed for a commercial environment + visible clock AND I am able to connect to Algo from any where in the world so support is much easier for me!
Thanks again!
Hello. How are you triggering the multicast? Are you using a relay to start and stop the audio out?
All the Algo devices are SIP endpoints, so I call the Algo8301 paging gateway with a software phone called MicroSIP, then the Algo8301 sends out the multicast streams to the speakers directly. Each speaker listens to a different multicast address, which is how it is possible to create separate paging zones. I use FreeSWITCH as my telephony server. This is all done on my LAN here in my lab.
@@boteman3428 oh yeah, I understand the sip server that is required in between to provide the routing and all that stuff. I was just trying to figure out if it's possible to automatically start a multicast stream when any audio stream starts to plays on the line-in. There doesn't seem to be a way to do that according to Algo themselves.
I don't want to leave the "always on" option because that just keeps the speaker on all the time even if no audio on the line in jack.
By the way, have you seen the grandstream sip speakers? They are pretty awesome and pretty cheap.
I'm trying to create a system of sip speakers in classrooms which can be adapted for analog audio using multicast. The Algo 8301 is awesome for that.
@@asmatec That's what I'm doing. That police scanner Line Output feeds the Line Input of the Algo8301 which is set to VOX operation. So when the scanner "talks" the Algo sends out the multicast stream to the lowest priority multicast zone, which Algo calls "music", intended for background music; you can see the blue lights illuminate. Any other multicast traffic that comes into the speakers is higher priority, so it mutes the scanner stream and allows the higher priority paging traffic to be heard over the speakers.
It is very flexible so it will probably do what you need. The Algo stuff is not cheap, but it is well-built and I have not found any bugs with the firmware. It can be managed via web browser for level adjustments. I export a text configuration file, then modify copies for similar Algo devices, then just load them in. It speeds up configuring many speakers in one sitting.
@@asmatec To be clear, FreeSWITCH is not involved in the multicast streams, only the higher priority call that overrides the scanner stream. When the SIP call is idle/non-existent the multicast flows directly between all the devices through the ethernet switch, no server involved. HTH
@@boteman3428 I haven't found a vox system of activating the multicast. Which place do I look for that setting?
Any for ships ?
Any for send outs haha ?
How and where can I get those from ?
