[Freeswitch-users] VoIP IP DSLAMs

[Tihomir Culjaga]

As for ADSL/VDSL CPE with FXS ports ... as someone said ... $40 - $300
depending of what is your setup. Whether you need VLAN tagging on the LAN
side, multiple PVCs, VLAN rewriting, IGMP, multiple bridges .. etc
All sort of additional features brings you 1 step towards that $300 mark :=)

my advice to you is to make it simple ... don't complicate things, don't ask
too much from  vendor... Initially you need to present him/them with your
network topology and the services you need to run on that CPE. They will
come back to you with the information whether they can or cannot do it ...
once they accept it ... make them work on the setup... just provide them the
lines.

good luck.
