[Asterisk-Users] Architecture Advice

[Chad Brown]

We have 2 offices. One is in the US and the other in India. We are
testing Asterisk as a possible solution. Does anyone have advice for the
preferred architecture when dealing with the latency from the US to
India?

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. It would be nice to leverage the sip phone
investment in each office.

I am open to any architecture and any protocol that will provide the
best reliability and quality between the 2 offices. BTW - we do have a
VPN between the 2 offices.

Thanks in advance!
