I am trying to accomplish the following. I would like to get a phone line from location 1 to location 2, presumably through a VPN.
I have a router from my ISP through which I get internet and phone services: the router has a RJ11 on it to plug in a phone.
What device do I need here to plug in to the phone line and then through a VPN get it to another device on the other side where I would plug in a phone? I have read about ATA devices and SPA3000s and SRP520/540 from Cisco/Linksys but not sure if these are the devices for this kind of thing?
Done it before. Where the line is, you connect it to an FXO gateway, where it needs to be you either register your PBX to the gateway or register an FXS ATA to it. Use a VPN in the middle like you said. Not too hard.
Now, a) your audio latency is going to increase and b) you need to make sure your VPN connectivity is robust, to avoid audio issues.
Okay, I have used this setup before with NO VPN . WOuld like to know your rationale for using a VPN
I assume you have no asterisk or other VoIP server. This is much easier with asteris, but here is the “no asterisk” hard way
You will need either a fixed IP or DYN DNS at BOTH locations (try duckdns, it is free)
You will probably need to open some router ports
NOTE : I will henceforth use IP address in place of IP address or DYNDNS name , so if you have an IP address that changes you will need to change it to a properly configured dyndns.
At Location 1 (where the phone line is this is a device with one fxo; phone and one fxs; line port))
Using an FXS & FXO ATA such as SPA 3000 connect the phone line and internet appropriately. You can also then use the FXO port to connect a telephone at this location too (it is best to find a device that will directly support your selected DYNDNS provider if one is required, as this will eliminate the need to run a DYNDNS updater elsewhere on the LAN.)
Set Location 2 IP:port address as SIP proxy:port
depending on device ;
SIP registration NO
Make call without registration yes
receive call without registration YES
Set SIP username to DID example 12125551212
Set SIP Password to PASSSWord (or any password you like"
Location 2 (where you want to extend the line to single phone port common ATA)
Set Location 1’s IP:port address as SIP proxy:port
depending on device ;
SIP registration NO
Make call without registration yes
receive call without registration YES
Set SIP username to DID example 12125551212
Set SIP Password to PASSSWord (or any password you like
You will need to pay attention to what ports the ATA is using and open them on the router accordingly , but unsure of behavior over your VPN
As you say the phone socket is on a router, I guess the service is VOIP from the ISP. If so, can you simply connect your own VOIP phone to the ISP’s service directly? If that is the case, could you connect to the ISP’s service using a VOIP phone in the other location, without any VPN?
Yes, the phone line is VOIP from the ISP and you can connect a phone to the port on the router at that physical location. How would you connect to it in another country? Also, I’m pretty sure if the ISP was aware, they would not be happy about it.
Your post was removed from r/VoIP for violiating Rule 4: Be reasonable.
We understand disagreements will happen, and we are not in the business of policing every discussion. However, attacks containing particularly high concentrations of vinegar will be removed.
You do not need to be nice, or express your points in a polite way. Just try to be a little less abrasive.
Find a provider that will port the number, maybe like voip.ms or something then configure an ATA like Grandstream HT802 or something and connect the phone to it.
To avoid the issues associated with a VPN, I suggest using SIP with Transport layer security (TLS) and optionally encrypt media if you want. You are going to have issues with a VPN. I too have done it, I’m a telecom SWE. It’s a pain.
If you know the parameters/credentials to connect your own IP phone to the ISP’s service, it would save an extra conversion to analog and back to digital. It’s possible that the ISP doesn’t check where/what IP address phones connect from but if they do, that’s where a VPN might be useful. But VOIP over VPN usually has issues e.g. latency.
Yeah but that is info you’d never be able to get. I checked in the router and it only has my number in it, in the VOIP tab and shows the VLAN. Nothing else, not clickable or anything. So I’d rather play it safe.
It’s probably a bit different here in Europe - I’ve been able to get SIP parameters for providers in the UK and Germany, when I wanted to use my own router and/or VOIP phone.
I don’t want to mess with any PBXes as this is solely a residential line. I want a device in and device out. I just need my landline with me wherever I go since I travel a lot to different countries for work.
I already have a FreePBX running at home with a GSM gateway to use my mobile number with a softphone app on my phone anywhere I go in the world and that was a pain to set up.
