Hi,<div>one reason for having that robotic voice could be improper codecs others include low CPU processing power, memory not free etc. I once had the same kind of issue with VAD(voice activity detection) turned ON from my service providers equipment so my asterisk was performing poorly with VAD. Asterisk version and its codec play more important role.<br>

Hello<br>
<br>
I'm using softphones as my only 'landline' phone service for almost 3<br>
years now (Diamondcard and now <a href="http://voip.ms" target="_blank">voip.ms</a>), so far using SIP (and mostly<br>
Twinkle). Also, I'm using Linux (Debian) as my choice of desktop OS.<br>
Also, sometimes I'm in networks with badly behaving NAT routers (for<br>
some time I used openvpn to solve this unreliably, then I ended up<br>
using 3G instead of wifi while in Canada, but now I'm abroad and don't<br>
have 3G). I'm now sufficiently fed up with SIP to give IAX2 another<br>
try.<br>
<br>
I want a softphone solution that:<br>
<br>
* works on Linux (Debian)<br>
* works reliably (e.g. remain connected for incoming calls, work with<br>
shitty NAT routers)<br>
* preferably encrypts both signalling and voice (dunno if <a href="http://voip.ms" target="_blank">voip.ms</a><br>
supports it, I might use a proxy asterisk instance on an own server<br>
instead)<br>
* properly handles audio with the 8000 samples/second dictated by the<br>
POTS systems (ALSA combined with some hardware (like both of my<br>
laptops) doesn't do proper lowpass filtering for mic input, so I will<br>
have to either use OSS or PulseAudio or rely on Asterisk doing proper<br>
downsampling in software).<br>
<br>
Asterisk seems to fit the first three; I'll happily build a GUI on top<br>
if this turns out to be a stable solution.<br>
<br>
My problems right now:<br>
<br>
- when I issue "console dial" without a number, it plays a recording<br>
with a woman's voice, and I can understand what is being said, but it<br>
sounds very garbled, like modulated with some about 20 Hz signal (a<br>
bit like a robot voice). What could be the problem? (Not using<br>
pulseaudio; +- default configuration.) One hypothesis I have is that<br>
it uses a too small buffer somewhere.<br>
<br>
- I don't understand how the extensions stuff is working. <a href="http://voip.ms" target="_blank">voip.ms</a> wiki<br>
told me to create sections named [voipms], but how do I switch to<br>
'default'?<br>
<br>
tie*CLI> console dial 4443<br>
No such extension '4443' in context 'default'<br>
tie*CLI> console dial 04443<br>
No such extension '04443' in context 'default'<br>
tie*CLI> console dial 004443<br>
No such extension '004443' in context 'default'<br>
<br>
- I haven't found anyone in google who tried to do the same as me,<br>
except <a href="http://www.junghanns.net/en/asteriskassoftphone.html" target="_blank">http://www.junghanns.net/en/asteriskassoftphone.html</a> but that<br>
doesn't lead me far (and the patch linked is unavailabe). Has anyone<br>
here done what I envision, or seen some docs specifically matching my<br>
use case?<br>
<br>
Thanks<br>
