OVH Trunk settings

Boris0x60 · June 10, 2026, 4:31pm

Hello everyone,

I am new to FreePBX (v17) and Asterisk (v22.8.2), and I am trying to configure a SIP trunk (provided by OVH).

I was able to configure the line on a softphone from my local network (the same network that my IPBX has access to, and it works).

OVH provides me with the following information:

Domain / Registrar

https://sip-domain.io

Outbound proxy

https://xxxxx-ovh-1.sip-proxy.io

I have tried almost every configuration I could find in FreePBX, playing with:
SIP Server, SIP Server Port, Outbound Proxy, From Domain, From User, Client URI, and Server URI, but I cannot get the status to show as REGISTERED.

I am probably missing a configuration step, but I have not found anything about configuring OVH with their new VoIP architecture.

Could you please help me?

Many thanks in advance,
Boris

Searching the forum I ran across a similar thread from a few years back. So maybe give this a look-see!

Hi,
Thank you very much for your response.

I looked at this discussion and I also saw some tutorials on the setup at the time, but it seems that adding the proxy is what is causing me problems.

Here are some of my logs, but I have the impression that it is the authentication that is not working.

When I see port 5060 I think the default for chan_sip, not chan_pjsip. As far as I’m aware chan_sip has been deprecated at the point of FreePBX v17, right?

Stewart1 · June 10, 2026, 6:16pm

Please try these settings:

Username: 0033123456789
Secret: (password provided by OVH)
SIP Server: sip-domain.io
Outbound Proxy: sip:xxxx-ovh-1.sip-proxy.io\;lr\;hide
From Domain: sip-domain.io
From User: (same as Username)

Note backslash semicolon in two places in Outbound Proxy.
If no luck, paste a new pjsip logger trace, but most importantly:

Post a screenshot of the relevant settings (mask personal info).

Hi,
Sorry for the late reply; I’m based in Europe.

Thank you for this lead. I tried to understand the difference between SIP and PJSIP, and it seems that one is the transport/signaling protocol while the other is an implementation/library that provides additional functionality, but I’m still not entirely sure I have understood it correctly.

I’m continuing to look into this topic, and I will also ask OVH whether it is possible to communicate using PJSIP with their SIP Trunk offering.

Thanks

Stewart1 · June 11, 2026, 8:27am

I had assumed, based on your 00331xxxxxxxx example, that you are in Paris. I’m in the 6ème, possibly within spitting distance

SIP is a communication protocol, now used by almost all VoIP systems. Asterisk has had two drivers. The older one, chan_sip, is obsolete and not present in V22, so I assumed that you are using pjsip and the suggested settings are for a pjsip trunk.

Boris0x60 · June 11, 2026, 9:38am

Haha, indeed, I am in France, but my actual number starts with 00335.
I’m based in Toulouse

Thank you very much for the clarification. If I understand correctly, PJSIP is therefore the library/driver used by Asterisk to communicate using the SIP protocol?

Here is a screenshot of the configuration that works with my softphone.

I changed the settings as you suggested. I no longer get the error message in the console.

However, when I try to place a call from an external number to an internal extension, I get the following errors, and the trunk status still does not change to “Registered”.

On the other hand, I can see on my OVH account that a session was successfully established when I applied the settings you recommended.

In parallel, here is the initial information I received from OVH support:

UDP session lifetime must be equal to or greater than 180 seconds
SIP ports to allow: 5060, 5080, and 5962 (UDP)
RTP port range to allow: 30000 to 40000 (UDP)
Disable the SIP ALG feature

Once again, thank you very much for your help.
Here my current FreePBX settings

I am puzzled – OVH knew the IP address to send the incoming call, so it must have been registered (at least at some point). What does Reports->Asterisk Info->Peers show for the trunk endpoint?

In any case, Asterisk attempted to authenticate the incoming call, which it shouldn’t have; it somehow didn’t recognize the trunk IP address. I have no idea why. Try these workarounds, in order:

Set Match Inbound Authentication to Ip.
Set Match Inbound Authentication to Auth Username and set Authentication to Both.
Set Match Inbound Authentication to Ip and Set Match (Permit) to AAA.AAA.AAA.AAA

The last one is not a long term fix, because if OVH changes the IP address of their proxy, it will fail.

david55 · June 11, 2026, 11:26am

You need a Match/Permit setting that matches all possible values of AAA.AAA.AAA.AAA (and nothing else). Otherwise Asterisk has no way of working out where the request came from, as AAA.AAA.AAA.AAA obviously isn’t one of the addresses associated with your Server domain name setting. You will need to ask OVH from which address blocks they an originate calls incoming to you.

Stewart1 · June 11, 2026, 11:34am

Makes sense, but I’m pretty sure that this used to be automatic, e.g., pjsip including the Outbound Proxy in the addresses that would match the trunk.

david55 · June 11, 2026, 11:43am

It’s not something that is done by chan_pjsip. If you want to match by address, you need an explicit type=identify section. It is FreePBX that defaults this to the server, and it doesn’t have the proxy in a form that can be directly used (and I think I did look at the code once, and noted that it didn’t use the outbound proxy).

Indeed, it may not be the cleanest solution, but option 3 works perfectly.

A big thank you to everyone for your help and support. Now that I have something that is starting to work, I’ll look into how to improve and make it more reliable.

Just to summarize in case someone else runs into the same issues:

The configuration shown in the screenshots works if you add “Match Inbound Authentication to IP” with the IP address of the OVH server.

Additionally, to make inbound routing based on the DID work correctly, I had to replace from-pstn with from-pstn-toheader in the SIP trunk configuration page (although this part is fairly well documented).

Hopefully this will help someone facing the same problem in the future
