[Asterisk-Users] SIP in the Philippines

[kurtz]

I have a frend in Manilla who is trying to connect to an Asterisk-based VoIP
provider here in Western Canada.

Has anyone had difficulties with SIP in the Philippines ?  I'm having a lot
of trouble getting info from the provider there (PLDT) and it seems as if
the device can't access a port that will allow it to get out and REGISTER
with the switchboard even because the provider never sees it make a request.

Is it possible that port 5060 is being blocked ?  I'm unclear as to whether
or not the required port must indeed be 5060 or if Asterisk is somehow able
to recognize SIP / UDP on any incoming port and correctly port forward it.

They're using a SPA-1001.

Thanks,
Kurtz
