Freeswitch + open vox G400P
i already have configure GSMopen for E1550 and it is working ok but the audio quality is not very good. Is there a way i can boost it or use openvox instead... Thanks, Kam On Tue, Jun 5, 2012 at 7:56 PM, Kamminthang Nengzalam < kamminthang.nengzalam@a-cti.com> wrote:

An E1550 is perfectly capable of giving the maximum audio quality GSM permits. If you are getting bad results perhaps you have the device in some dark corner with a weak signal. Steve On 06/06/2012 12:06 AM, Kamminthang Nengzalam wrote:

Yep freeswitch sound quality is awesome n i am loving it. :-) Well regarding my gsmopen, i run it in my local desktop ubuntu. and login to the gsm using x-lite and a made sure the x-lite have gsm codec. after logging to the x-lite a dialout to my cell phone and sometime a will not hear the ringtone on my x-lite and some times no audio. The same goes for when a call my gsm which i configure to ring in my x-lite. Hope this helps. Thank you guys.

Kam: -do not use gsm codec, no need for it, and sounds bad. Use ulaw (g711) or whatever - do not use a desktop as a server. It will never work decently. X Windows, mouse, dozen of other things will battle for IRQs, and this will trash all the millisecond timers real time audio needs. so: -use a server installation also, is kind of tricky to run both the sip client and the sip server on the same machine (ports, ip addresses, etc). Better to use separate machines -giovanni
Hope this helps. Thank you guys.

In which way audio is not good (it's straight from the digital stream, so it's exactly how the carrier give it to you) ? Can you elaborate on this?

definitely not -- Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618
Maybe you've gotten used to the superior sound quality freeswitch provides :-) Your audio quality is dependent on the equipment you are using, and the E1550 is a good piece of equipment. Check your signal stregnth and make sure you are giving the equipment the best chance of working. If that device doesn't have an external Jack then USB port extenders work wonders. Just remember that GSM isn't a high quality codec. If your phones take GSM (most IP phones do) then make sure GSM is being used end to end (I.e. no transcoding). That might yield better sound quality, and you should be doing this to decrease the load being placed on your system. Brian Foster Endigo Computer LLC Sent from a mobile device.

No, there is no transcoding to/from GSM codec with mod_gsmopen. mod_gsmopen takes a digital stream in signed linear (SL16) at 16 bit, 8 khz directly from the modem. It's the modem chipset that digitally converts from GSM codec to signed linear. So, mod_gsmopen passes to FreeSWITCH the SL16 stream 8khz, without touching it, in its purest form. But it's true that if you're used to use FreeSWITCH with 16khz (or superior) codecs, then you can be spoiled ;). -giovanni -- Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618
