Zitat von A J Stiles <asterisk_l...@earthshod.co.uk>:
If I call a phone at home using my cellphone it works and the quality
is perfect!
If a phone at home call my cellphone, however, the quality on my
cellphone is very poor, but on the other phone is perfect...
I think, it is something by the codecs, but I don't know what...
Codecs would be the first thing I would be looking at.
Me too... :)
The "native" codec used by the PSTN throughout Europe is G.711 A-law, or just
alaw for short; and if you are making a system which connects with the PSTN,
there is rarely a good reason to use anything else; since something,
somewhere
Well, PSTN (and ISDN) in Germany will be shutted down in short...
That's why I'm experimenting with Asterisk now... :)
-- and most probably *your* Asterisk server -- is going to wind up having to
translate from one codec to another. That is going to (1) take a finite
amount of time and (2) introduce distortion.
Try, in the top section of your sip.conf file,
disallow=all
allow=alaw
And that ought to fix it.
I wanted to write the list again, since I maybe got it just adding
"allow=all" for the user...
I'll try your configuration this evening, too and report to the list...
I'm very happy, that now I can login in my Asterisk at home and I
don't need another Asterisk on a separate server.
Firewall can be very difficult to setup, sometimes, for a SysAdmin as
I be, too... :(
