Is there any location specific settings I should be aware of when setting someone up who is located in another country?

I have a user who needed to return home for an extended duration. We set him up with a new laptop, and tested a softphone on the laptop before he left.

He lives in a semi-rural area in the Philippines, and currently taps into his neighbor's network (with permission) via an ethernet cable. The ISP is "PLDT", and they provide a modem/router combo that is currently in use. For whatever reason, PLDT won't install a line directly to him, and I get the impression this is a common practice where he lives.

The ISP provided network device leaves a lot to be desired. Every time you need to change anything even semi-serious, you have to go through this convoluted process of resetting the admin password, and logging in through a different series of pages.

Anyway, the common theme I've read up on is to disable the SIP and RTSP Application Layer Gateway (ALG), then add in the port rules manually. When I do that, I immediately lose connection to the PBX server.

So, I'm confused as to how to proceed with this. Everything appears to be functioning, but we can never hear one another. I've tried different codecs (even though the selected codecs worked before he left), messing with his Windows Firewall, and different combinations of ALG settings and port settings.

What would you do in my shoes? I have SIP traces, but there doesn't appear to be any red herring where those are concerned, though (admittedly) I don't know what I'd be looking for. I'd be happy to provide a sample if requested.

PS. In case it wasn't obvious, I've set him up with a DDNS service and tested and configured WAZO to make sure his remote IP is accepted. There appears to be no issue where that is concerned.

In some countries the SIP port is blocked.
Can the softphone register to the PBX? You will also need to forward UDP ports for the audio path.
Another alternative is to create a VPN from his laptop to the network where the PBX is installed.

I second a VPN or if you can try IAX. PLDT is a pain to deal with when is was there, they are the incumbent. I'd say try Digitel as as alternative ISP but PLDT bought then a while ago.

Apologies for the delayed response...

We did have registration at one point, but he's been relying on Skype for the time being. He was approved for his own line, so I am hoping the tech there can setup his modem in bridge mode to remove it from the equation.

Regarding VPN

He's currently connected to the local office through a tunnel, but we don't have great hardware. I doubt the throughput wouldn't be enough to satisfy a consistent enough connection.

However, our PBX isn't located in the office, it is hosted by Vultr. I could probably setup a VPN server over there if we can't get him connected any other way.

Thank you both for your feedback, I will update this again as things progress!

I second a VPN. In some countries, they use DPI and not even port changes or IAX get through, even worst is I've seen it work for a short period before it gets blocked. A solid VPN is about the only way around.
