Yes, been a bit busy here - the financial year ends here on 5th April and so its panic time to try and get all the sites on the air! Thanks for all the info in your email - I'm still a little unsure of a couple of things so please bear with me .... I can edit the crontab as you suggest but how do I control App_rpt from the crontab? What do I put as the command line to make Asterisk play out the file? I assume I have to use root's crontab? In your dialplan example, I see the extension referred to is 96 - is that the DTMF code I dial to activate that script or do I need to put something in rpt.conf to call to the dialplan? You say you can call the playback command from the cron and / or the dialplan - how does one do this and what DTMF code or other trigger can be used to call the playback command? Thanks again for your help Ramesh and sorry for the (still) noob questions! Still trying to get my head around how app_rpt and Asterisk stitch together! Cheers and hope to speak soon.

Replacing an IRLP node with App-rpt node
by Matt Beasant 30 Mar '09

30 Mar '09

HI all and welcome to the new list! Thanks to those involved in setting it all up. My App-rpt node has replaced an IRLP node and is working great, but I used to have certain facilities on the IRLP node that I am attempting to replicate on my app-rpt node and I'm struggling! 1, I had a script that unlocked the controller at a set time every day and set the time using DTMF - now I know that ap-rpt cant generate DTMF (yet) but I could use WAV files as the digits will always be the same and the time the script gets called will always be the same. So my first question is, how do you call an external shell script from within app_rpt? Perhaps from the scheduler available in rpt.conf or some other method of calling a script at a set time, maybe from a cron somewhere? Can it be done in the dialplan by dialling a specific extension or some other cunning means? 2, I used to have the popular "playnews" package running on the IRLP node, which downloaded certain news files and played them out at pre-set time. I use these scripts to play out the GB2RS news files through my repeater every week. I have tried to replicate how this was done on the IRLP node but am having difficulty automating this process. I have used the Asterisk command line invoked "playback" command which works but I'm not happy with the audio quality and I had to manually trigger the playback from the CLI. So next I tried the WAVPLAY program that seems to be used to play out IRLP node announcements and the quality was great but I kept getting node timeouts from the IRLP software ( I guess ) as my APP-RPT node has no timeout. I thought about mpg123 as used in the IRLP playnews scripts but cannot find a way of keying up the repeater - I'm not sure if the audio from mpg123 would come out of the USB radio interface! Any ideas, suggestions or solutions would be most gratefully received as I have currently run out of talent!! Thanks, Matt G4RKY Node 2250

[App_rpt] irlp audio vs asterisk audio (channel drivers)
by James Nessen 30 Oct '08

30 Oct '08

I recently setup a node for a buddy of mine and we moved him to the channelized irlp and echolink installation. He has recently received poor audio reports from the IRLP side of his node and we did a A/B test one night on his audio. I found that his Asterisk audio is great, and is full of audio (our two nodes connected via uLaw). leaving the volume on my HT, I disconnect from him via AllStar and then connect up to him via IRLP. His audio on the IRLP side is about 10% lower than his level when were chatting via AllStar and also sounds muffled. Has anyone else noticed this? If so, is there a fix for it? Thanks. Jim / K6JWN AllStar Nodes 2142 and 2165

Matt, No, not yet. If the channel driver gets loaded, it will be enabled in app_rpt.

[App_rpt] CPU Load
by John Yaldwyn 27 Oct '08

27 Oct '08

Hi All, Recently there was a brief discussion as to CPU performance. Over the weekend I had the opportunity to look at the CPU loading of two systems I run. Both systems are built from the ACID distribution with the following changes: Node update script disabled Sendmail disabled Digium G.729 codec loaded Admin and Webmin interfaces disabled Required modules only loaded Neither system uses Iptables and both are located behind Linksys BEFSR41 routers with fixed IP addresses. 'netstat -ta' shows only the SIP, IAX2, and SSH ports open. Both systems uses IBM Serve RAID hardware RAID level 1 using 18GB 15K RPM drives. System 1 consists of an IBM x345 single CPU PIII-S 1.133MHz Server with 512KB cache and 2GB RAM. 'less /proc/cpuinfo' shows BOGOMIPS of 2257. 'top' shows and idle CPU load of 10% for asterisk and negligible load for any other process. 'free' reports about 419KB used. 'swapon -s' reports swap space usage of 0. With on USB connected repeater active (ongoing voice conversation) and an independent voice call set up using a Linksys SIP telephone set using A law codec connected to a service provider using IAX2 and G.729 top showed a peak load of 22%. System 2 consists of an IBM x345 single XEON 2GHz HT capable Server with 512KB cache and 2 GB RAM. 'less /proc/cpuinfo' shows BOGOMIPS of 3990. 'top' shows and idle CPU load of 6% for asterisk and negligible load for any other process. 'free' reports about 500KB used. 'swapon -s' reports swap space usage of 0. With on USB connected repeater active (ongoing voice conversation) and an independent voice call set up using a Linksys SIP telephone set using A law codec connected to a service provider using IAX2 and G.729 top showed a peak load of 17%. Looking at the numbers the higher performance XEON system seems to have made only a marginal improvement at what is admittedly a light load. But what is more interesting it appears that relatively modest PIII boxes are fully capable of managing the single repeater type applications without resporting to something like Limey. Perhaps PIII 500MHz or more, 768MB RAM, and 2GB or more disk as a working minimum spec. Note that the Anaconda installer used for CENTOS in ACID seems to have problems loading with just 512MB of RAM. I would be interesetd to hear from anyone running such a configuration. Using the simple shell comands shown in single quotes above provides a quick system overview for basic performance evaluation. Cheers, John ZL4JY
