[Asterisk-Users] Zyxel Prestige 2002/2002L sound quality
Hi everyone, I've been trying a Zyxel Prestige 2002L ATA with Asterisk, but I have a problem with very bad sound quality (using G711, it sounds very "robotic" and metallic) and there is a very long delay in the audio. This all doesn't happen with other ATAs (like the Grandstream HT286). Apparently there are no parameters you can set. I already have the latest firmware installed. Could it be a defective unit? Does anyone have experience with this ATA? Thanks -Manuel -------------- next part -------------- An HTML attachment was scrubbed...

Zyxel Prestige 2002/2002L sound qualityHi,
This ATA works fine for us.
Haven't had any problem with sound issues, other than 1-way audio, but that
is another problem which is fixed.
But checked with different analog phones, and there seems to be a difference.
good and bad quality.
Doro 530, and Siemens Gigaset A11 works ok. But the Doro Palermo is shitty :)
Have you check it works (not work) with asterisk, but _also_ with another sip
operator ?
(can you u try connecting the ZyXEL 2002 to a Free World Dialup ?)
