Subject: Re: [Freeswitch-users] Raspberry Pi, mod_gsmopen GSM dongle
Sergey I tend to agree with the statement in your first post, it's a shame that Asterisk works better
in your setup. 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.
