asterisk users - Mar 2006 - 2-Asterisk@Home Servers Connecting Portugal to Brazil (offices)

Hi all,

I'm planning to connect 2 office from one company.

I'm the developer, so i hope i can get all the features working well.

Ast@Home(Portugal)---------IAX2/VPN--------Ast@Home(Brazil)

1- First i'm integrating Asterisk in Portugal's company office, one
Asterisk@Home with TE110P connecting to an old PBX. (the same is done
in Brazil, but only VoIP no TE110P)

For *@Home PCs:
-P4 1GRam 100GHard Disk
(About 20 to 50 users initially)

2- For Portugal internal VoIP calls as well as VoIP to PSTN i think it
would be all ok.

I would like to hear from you? (using Alaw will I need QoS on our LAn?
we have Gigabit Lan)

Main doubts are the the connection between Brazil and Portugal. Will
it work only using IAX2 and Alaw?

Will I need G729 for this connections? Does DTMF works fine with G729?

(I'm planning maximum 4 simultaneous calls to Brazil)

We have broadband connection 4Mbit.


I hope this Excellent mailing list could help me on giving me some
Feedback and or advices/tips.

Best regards,
Marco Mouta
