Bleeping Hub
by David Osborn 07 Aug '13

07 Aug '13

Hey gang, Just goofing around, I wanted to see how well Allstar would play when configured as a hub node under VMWare. Well, it worked and I was able to make connections to other nodes, connect with IaxRPT and all that good stuff. The thing is, it likes to beep. When I connect the virtual hub to another node and then key that node, when I let go the button I get 6 rapid beeps followed by the courtesy beep from the node I'm accessing. I believe that these beeps are coming from the V-Hub, but can't figure out why. Anyone got any ideas on this one? Thanks David - GD4HOZ

I disabled all CTs and also copied the rpt.conf from node 2483, which has run as a hub for a couple of years, and yet it still bleeps at me!

Hello everyone, How do I setup my node to say time every hour. I'm using Acid on a neoware ca22. And where should I put it? N5zua sit this up for me a few years ago. So, seems to me, I need to to know the system and play with it. Thanks, Larry, n3vsi

Asterisk module for DTMF control
by Mihhail Jakovlev 07 Aug '13

07 Aug '13

Hi, I need a help... I need to build a small system with amateur simplex links with low cost and low power nodes with any PBX functions (gsm trunk, voice menu, mailbox). PBX server based on XIPPR, but may be a Freeswitch too. I need to use only SIP protocol. System programmed using inbond DTMF. Hardware may be a Raspberry pi, with USB soundcard for audio and USB-UART adapter for radio control. Idea is a DTMF control. Any Asterisk app or module need to code and decode dtmf digit (letter) PTT activate with DTMF "A" and deactivate with DTMF "B". For example, node number 2000 connected to node 3000. If to node 3000 audio input comes DTMF letter A (from radio channel), it will activate PTT on node 2000 and letter B will deactivate PTT. One UART pin can be used as PTT, second as CarrierDetect. If CD pin grounded (radio channel buzy) node generate DTMF tone A for activating PTT of second side radio (or radios, if used conference). If CD pin ungrounded, node generate a B tone. This system will be very simple, possible to use different server platforms, gateways, node cost is Raspi 40eur, USB audio and UART is 8eur Same system in Freeswitch tested and works very fine! Could any help with making this addition module? I think, it may be interesting for other voip/roip users Thanks, Mihhail ES1BIS

Connecting Nodes

First since it is not driving anything can a Raspberry Pi act as a Hub running the current release of Asterisk (i.e. apt-get install asterisk) ? Or do I need to generate a Centos Based Hub, and where in the documentation is do ing so, I looked but haven't found that yet. If I can use a current version of Asterisk, rather than app_rpt how do I configure it? Next how do I link nodes. Assume I have a hub with a node number of 1010 and three remote base stations with node numbers 1110, 1210, 1310. Assume I will be using the iaxrpt client. When I press transmit on the iaxrpt client I want the transmission to go out on the three nodes. If there is a transmission received on either 1110, 1210, or 1310 I want it to be received by the iaxrpt client, and transmitted out the other two nodes. I am not sure if I need the hub, as I was told that 1310 can attach to 1210, which can attach to 1110, and the iaxrpt client can attach to 1110 as well and it will all work. I haven't found the documentation on how to get nodes to attach to each other, or how to configure that. I would very much appreciate someone pointing me to the right documentation so I can try to set things up. Thanks in advance, Barry, K0BSB Sent from my iPad

I use the AT&T site and just type what I want the message to be. Pick the voice and listen before I spit out the ulaw audio file. Had my whole IVR system menu done that way. It was mint.

If the original wav file is not limited to -6 dBfs (minus 6 dB relative to full scale) you can reduce the level "on the fly" by using the lower case "v" for volume control. For example, this reduces the volume to half what it was (-0.5) sox -v -0.5 -t raw -U -c 1 -r 8000 (etc...) 73 Ken > -----Original Message----- > From: Angelo Glorioso [mailto:n5uxt@hotmail.com] > Sent: Monday, August 05, 2013 10:39 PM > To: Ken > Subject: Re: uLaw playback > > Hi Ken, > > Thanks for your reply.

uLaw playback
by Ken 06 Aug '13

06 Aug '13

I have read where uLaw produces 14 bit audio (-8159 to +8158 numerically-speaking) - see Wikipedia on this, for example. I am guessing this is the range of numbers used by app_rpt. Your 16-bit WAV format is going to produce +/- 32768 (numerically-speaking again). So - you need to divide the WAV output by a factor of 4 to get into the range that uLaw supports. The tutorial on using Audacity for app_rpt: http://images.ohnosec.org/app-rpt-audacity.pdf says to normalize at -6dB. You really need to follow that advice to get clean audio. "Normalize" will set the loudest sound to the amplitude you select. If there are a lot of sound "spikes" in the audio track, you can end up with a pretty low average sound level. I have found the best way to fix this is some judicious use of the Audacity "hard limiter" function. It really does not damage the sound quality, when used within reason. 73 Ken
