[Asterisk-Users] asterisk voip only solution

[Miranda Gomez Miguel Angel]

Hi people, is there any good document on setup asterisk using only its voip
functions , i mean without e1/t1 hardware, i have a cisco 5400 gateway and a
cisco 7000 working as gatekeeper, can asterisk register with this GK?, im
thinking in using cisco voip phones
Any pointer will be apreciated, and sorry for my bad english
Miguel
