Hi Noggers,<br>
<br>
We've recently been tasked with assisting getting SIP running from
Australia to the
<meta http-equiv="content-type" content="text/html; charset=utf-8">
Philippines for remote staff workers on DSL tails. SIP server is in
Sydney, behind Vocus transit.<br>
<br>
It appears that CGNAT is a hurdle, plus 350-450ms of latency, and
the inability to obtain a static IP on a 'residential' grade tail.<br>
<br>
We're now using Fortigate SSL VPN tunnel as a solution, and just
routing the SIP server down the split tunnel, but not sure if this
really makes the situation worse or not, and I'm looking to hear
other ideas and battle stories!<br>
<br>
What are people using out there to deliver a reliable service that
sounds good? -plus:<br>
<br>
- Get around CGNat RTP Audio/SIP transport issues<br>
- Ensure SIP server is not open to the world due to dynamic IP's
connecting<br>
- Keep the bandwidth requirements to a minimum - Assume low speed
DSL (2M/512k)<br>
<br>
Direct carrier links are not a possibility unfortunately as the
staff all work from home offices.<br>
<br>
<br>
<br>
Cheers,<br>
<br>
Luke<br>
