[asterisk-users] can I get a little criticism?

[Alexander Benaguev]

dear list

I'm very new in telephony and asterisk especial. so, it would be great
if somebody see at my dialplan. it works (except e1 which is untested at
this day), but I think it's not perfect. thanks

alexander

p.s. in Russia national prefix is "8" and international "810"
