This breaks every rule in the book but works given the user understands
the one way speaking on the phone. Take a look at the NM1-VSAT-GILAT
and what it can do in this scenario. Have customers setting up voip
over satellite to oil rigs/platforms also some cruise ships who use ip
phones over satellite when they are moving and switch over to some other
form of WAN when docked. There are some things to look out for phones
registering and not having to reset.
What are u using for hardware?

U donot need CME ,voice gateway with FXO or E1 will work fine.
Nice to hear that voip works over the satellite.Experience speaks.Cisco
does not recommend it over satellite but if u people r not facing any
jitter and delay ,fair enough.

Great,
Well thanks a lot for all of you guys for the valuable information, I
spoke to customer he has no problem with nominal delays or echos, but
the problem is he doesnt have IP telephony, for the first time i am
going to introduce VoIP. so they want complete integration because they
have one site in Dubai, one in Egypt and the Head office in Riyadh.
I dont know what PBX they have in remote sites but here I think they
have NORTEL, we need to integrate VOIP with these PBXs so that they can
use any phone extension to call any remote site, and this should apply
to all sites.
I will be getting more information from the customer and i will post it
if needed, now guys how can we integrate, shoul i use CME on cisco
routers or FXO cards are enough.
Waiting for replies.
