PLDT SIP Trunk (Philippines)

[joerbrando]

Hello everyone,

I have been bashing my head around how to configure a SIP trunk here in the Philippines.
Does anyone have prior experience on doing this?

According to my research, this is the setup they are using:

Multiple internet gateways (used by ISPs that offer VoIP Services)
https://www.3cx.com/blog/docs/network-configurations-supported-3cx-phone-system/

And the guide that i have followed to try to get it setup properly with 3CX is this one:

Configuring Singtel SIP Trunk in 3CX (Just replace Singtel details with PLDT details)
https://www.3cx.com/docs/asia-sip-trunk-singtel/#h.evect8xdd3qr


Im not even able to ping the SBC, which i assume that i should be able to do?
And PLDT has of course been less then helpful regarding this since they say that 3CX is not a "type approved PBX", even though i know other companies here in the Philippines that are using this very setup.

Check if you can ping the host/provider. It should be reachable first from your premises before you can establish a SIP Trunk registration.

Thats what i suspected as well, and i cant even ping the device or any of the addresses that has been supplied to me. I assume they must have done some kind of misconfiguration somewhere on their side.
