Imposibilité de Configuration ligne SIP avec le nouvelle infrastructure N11 (VOIP decouverte)

Bonjour,

Je n'arrive pas à configurer le telephone Yealink T31P avec les parametres "Informations SIP" de la nouvelle infrastructure N11 indiquent le domaine : sip-domain.io et comme proxy : "compte client-1.sip-proxy.io"

"Etat de l'Enregistemenr ; Echec du registre"

Le telephone fonctionne tres bien pour une autre ligne Voip OVH de mai 2024 sur le domaine sbc6.fr .... et proxy = domaine

J'ai fait le test aussi sur un autre telephone IP , sans succes non plus.

Mon infrastructure : telephone branché directement sur Box OVH : TG788vn

Auriez vous des idées?

Bernard

Bonjour

.. avec les paramètres "Informations SIP" de la nouvelle infrastructure N11 indiquant le domaine : sip-domain.io et comme proxy : "compte client-1.sip-proxy.io"

Je ne pense pas que ce soit les informations de configurations données par OVH.

Prenez celles données par OVH et testez sur votre Smartphone en suivant mon guide.

Bonjour à vous deux,

@ Gaston Je confirme que ces informations proviennent bien d'OVH car j'ai les mêmes que @Bernard electro .

Mon contexte est différent (Freepbx) mais le symptôme est le même avec un rejet de l'enregistrement.

Bonjour

Avez-vous essayé sur votre téléphone mobile en suivant mon guide avec les nouveaux paramètres .io fournis par OVH en suivant mon guide ?

Bonjour,

Oui, pour moi cela fonctionne.

D'ailleurs, pour faire fonctionner sur Freepbx la nouvelle infrastructure OVH et le Outbound proxy, la valeur "sip:cm31283-ovh-1.sip-proxy.io\;lr" à fait l'affaire.

Est-ce que cela peut aider Bernard ?

Hello,
I have the same issue—unable to connect FreePBX to an OVH SIP account with the new N11 infrastructure.
I've been using OVH SIP accounts for about ten years with other infrastructures, but this one with its proxy is a nightmare to configure.
Especially since I have no idea which OVH genius changed the help links...

In the outbound proxy section I put "sip:sh249261-ovh-1.sip-proxy.io;lr" but nothing works.
Does it work at least for someone using FreePBX/Asterisk?
Thanks
Best regards

Alex

Hello @Alex2

Personally, whether it's 4G on my Android phone or Wi‑Fi on my Windows computer, I never set a proxy for the discovered OVH SIP configuration.

Hello @Alex2

I didn't quite understand exactly what configuration you want to set up, between the other box and the OVH line type.

Which version of Freebox?

Where are you installing the OVH SIP line?

Hello Gaston,
Thank you for your reply, but I didn't choose to set a proxy
this is the configuration that OVH gives me unfortunately with this new N11 infra:
SIP account:
Login / User name : 0033xxxx
Password : appropriate password
Authorization user name : 0033xxxx
Domain / Registrar : sip-domain.io
Outbound proxy : sh249261-ovh-1.sip-proxy.io

In any case this server exists, under different names

~# ping sh249261-ovh-1.sip-proxy.io
PING asbc.n11.prod.nowi.ovh (137.74.239.8) 56(84) bytes of data.
64 bytes from ip8.ip-137-74-239.eu (137.74.239.8): icmp_seq=1 ttl=53 time=15.2 ms

Hello Gaston,
I want to set up an OVH SIP account in FreePBX, then I have phones that connect to this FreePBX, with call groups, IVR, etc.

Hello,

After many attempts, I finally figured it out.

Outbound Proxy: here you need to set sip:\;lr

and especially

Trust RPID/PAI a yes

Send RPID/PAI a both

rewrite contact a yes

Thank you

I move forward, walking on eggshells, with the idea that using a proxy is necessary when the registrar is sip-domain.io (because this domain seems unknown to DNS).

Same problem on a Gigaset 530 IP (up to date)

With the domain sip-domain.io it cannot connect via SIP.

On a Fritzbox 7590 it works perfectly.

I have already tried every setting available in my OVH client interface. OVH also refuses to give me any help on this.

because: “not purchased from us” :partying_face:

But it is stated in their documentation! It’s just that the information is outdated!

Is there a solution to this problem or should I toss the Siemens Gigaset 530 IP?

Hello @satsurfer

Just in case, try:

@Gaston_Phone Gaston, I’ve been following your instructions for several days. I even contacted you and sent an email, but I haven’t received any response.

I have a doubt about the use of “always” of the proxy “sip-ovh.io”.

Were the codecs authorized? G.711 law A at a minimum (we can authorize all of them, it doesn't hurt).

We see that the registration succeeded, so what is not working?

Yes, it's a fake screenshot, I'm still using sip-domain.io
