[asterisk-users] sound quality between two back-to-back asterisk

[mark morreny]

Hi,

I have two asterisks that are connected to each other via a back-to-back E1
link using a pair of sangoma cards.

With the following scenario:  SIP-PHONE <-> Asterisk <-> E1 <-> Asterisk <->
SIP-PHONE, the sound quality degrades significantly.   I can't understand
why as the amound of packet lost should be very minimum.

Does anyone know why?  Does it have anything to do with what codec to use?

Thanks,
Mark
