<div>If your remote workers are on the dominant
Philippines carrier PLDT, your first step will be to
shift your SIP server to a transit provider with better
routes to the Philippines. If they're on Globe, the same
measurements can be done - I'm happy to show you how to
set them up.</div>

It's not only your transit provider, the traffic back matters too.<br>
<br>
As an example, I have a /29 on my PLDT fibre connection. Testing
from two different IP's in that /29 to the same destination in AU
results in a difference of 120ms! The route leaving AU is the same
for both, the route TO AU from PLDT is different starting from the
third hop. On Globe it is the same latency across all IP's in the
/29 with them.<br>
<br>
Luke: If you want me to do any testing for you I would be happy to
help as well (from my Globe and PLDT connections, business fibre
and ADSL). If you use RIPE ATLAS I also have a probe setup on my
Globe fibre connection, chances are you will be using that if you
select Philippines.<br>
<br>
At the end of the day I would never use a single ISP unless I was
willing to put up with down time and/or excessive latency. I have
used 6 different ISP's here so far (fibre, ADSL and wireless PTP
link) and not one has been anywhere near as reliable as the iiNet
DSL connection I had back in Australia. Just today there was a
power outage, my PLDT fibre link had no outage but the Globe one
did. Obviously the Globe one is missing a UPS somewhere in their
network...<br>
