[Asterisk-Users] asterisk, fwd, and grandstream?

[hank smith]

hello I want to use my grandstream witch is currently configured for fwd to
use asterisk, my asterisk is configured with fwd threw iax, but I want to
still recieve calls on my grandstream threw fwd threw asterisk if this makes
any sense is this possible?
I basicly want all of my phones to use asterisk but be able to use them with
all the networks, my fwd account, my broadvoice account, etc etc. can this
be accomplished?
thanks
