[Asterisk-Users] Performance on VoIP

[TC]

>Also if anyone had used the Adtran Total Access 750  can you give me
>some opinions about it ?
-quite stable, factory default setting work out of the box with zaptel T1
h/w
  pass's callerid etc
-any firmware version prior to L34 would not properly support far end
 disconnect supervision for me
-L34 will not retain the MWI flag on a power cycle
-if you are with in 2-3  miles of a strong AM radio station transmitter
 and using standard L1 or L2 FXO cards you will have RF interference
 you gotta call adtran for special L1 modded FXO cards in that case
