We're in PK, latency to US is around 300ms (not including our local-loop, which depending if the BRI wants to cooperate or not, ranges between 30 and 140 ms) (so between ~300 to ~400ms latency) * still sound bloody great... use iLBC over IAX2 (trunked if more than a handful of calls between the two points). For a single call budget around 24kbps, with more trunked calls, add the cost of the codec per call, plus a slight overhead. > For example, although it is not a requirement to have an Asterisk server > in India it may make sense to have one there and connect office to > office vi IAX since I hear that it supports low bandwidth / high latency > connections better than SIP.

I would put an * box as close to each end-user as possible, that'll ensure that atleast all their local options (menus, voicemail, AGI) are not "bandwidth dependent". > I am open to any architecture and any protocol that will provide the > best reliability and quality between the 2 offices.

US SIP -> US * -> IAX2/iLBC -> IN * -> IN SIP it doesn't get any better than this :) enjoy, welcome to * - wasim _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
