Hi! Not so bad FS I still work with the module gsm_open, sometimes it is not clear why the device is heavily loaded. load average: 4.07, 3.99, 3.96 Now I want to watch CPU module with or without gsm_open. I want to collect data using sar and show to the public. The sound quality is not very much, but like a normal. use Raspbian Linux raspberrypi 3.6.11+ #538 PREEMPT Fri Aug 30 20:42:08 BST 2013 armv6l GNU/Linux For I am not afraid that the long compile, just to work with dignity;-) From: Johannes Stads <stadsj@yahoo.com>

But i think there the problem is not in Freeswitch. The problem is in gsmopen module, in its features and support. I made a question about gsmopen back in september, and did not receive any answer. Gsmopen is in a beta state, we should not require any stable operation of FS with gsmopen module in a production environment. I have a long experience with Asterisk, and decided to give a try to Freeswitch to see its superior performance. I started using a linux virtual machine. Then tried it also with BeagleBone Black which is just a bit more powerful beast than PI. All compiled well, including the latest version of FS. Building of a mod_gsmopen was a bit of a pain, but finally worked too. What linux flavor were you using with FS on PI? In my setup I used bare minimum config, and again can confirm that FS is a superior platform with plenty of advanced features, though its concept is more difficult for understanding initially. Although I was able to send SMS and make calls out of the box, gsmopen worked highly unstable and sound quality was not good, to say the least.

To prove my concept, today i took a fresh SD card to put Debian Wheezy on it and installed Asterisk with chan_dongle. The platform used was BBB. What can i say, the experience was different. To compare, FS build time on BBB/Debian/SD card was such: ./configure (about 1h) make (about 2h) Asterisk was up and running in about 30 min. chan_dongle was built smoothly without a need to tweak libraries.

In my FS setup gsmopen did not show a claimed 'auto discovery' feature and some exercise with UDEV rules was required to make sure that modems are loaded in right order. In chan_dongle it is nicely done out of the box.

Overall, chan_dongle is much more advanced piece of software, I want to use this opportunity to thank its author. If your goal is calling to mobiles, you have to consider chan_dongle against gsmopen, and not FS against *.

Cheers, Jo

I am glad to tell you that: 1) mod_gsmopen and e1550 work on Raspberry Pi (incoming, outgoing SMS in both directions).

2) and the stable version FS and the latest FS compile on Raspberry Pi, but it's a long time.

3) The latest version does not run on my raspberries.

Need advice on optimizing the FS for raspberry Pi, as low-productivity device.

Can any startup options? Maybe someone knows what modules you can disable resource-intensive.

Something else?

Does somebody have a positive experience with Raspberry Pi, mod_gsmopen GSM dongle ???

I use Raspberry Pi B and e1550.

It's a shame that with an asterisk all works fine -- RasPBX. http://www.raspberry-asterisk.org/

But I prefer the FreeSWITCH ;-) On the basis of experience, I thought that PS will work best for this modest hardware faster and require fewer resources.

But it turns out it is not. Asterisk with a web server, MySQL database, and other, less load than FS.

In this connection, other parameters may be used starting FS to save resources?

And the main question! Silence an incoming call on 5000 (IVR) as well as an outgoing in gsm network. Those are not sound.
