[asterisk-users] Cisco vs Asterisk

[Grygoriy Dobrovolskyy]

Do say no more, thank you Alex i think a majority of users here think the
same, i suspect that Alan Baker is the kind of person who defends his
position no matter what it takes, and facts dont change that much, look at
other topic at this list here 'Cisco Call Manager to Asterisk conversion'
Same argument without and explanation.
