Re: [OpenSIPS-Users] SIP user statuses to websocket
Hi Bogdan, Thank you so much for the guidance. I have gone through the link and added some custom events. I am able to subscribe and send them to an interface. The document for jsonrpc event is broken. If you go to Transport Protocols and click on event_jsonrpc <http://www.opensips.org/html/docs/modules/3.2.x/event_jsonrpc> it says Not Found. can someone fix this link, please? I just want to look at the json rpc events. Thank you. Regards, Jazzi On Fri, Oct 21, 2022 at 1:47 AM Bogdan-Andrei Iancu wrote: > Hi Anonymous, > > Check the events interface in OpenSIPS [1].

[OpenSIPS-Users] SIP user statuses to websocket
Hi all, I am looking for a way to use WebSocket with opensips. Basically, I want to show my all sip users statuses/activity on a web page. I am currently using an API, which is called after a few seconds so this is a bit slow. I am looking for a way that opensips sends event to the socket and on the other hand, my webpage will be connected to a WebSocket server. This way I can show all the events instantly. For example, If a user receives a call I will have it on the web page straight away. if a user gets unregistered i will see on my page that users sent Expiry 0 something like that. Will it be possible with the proto_wss module. any pointers will help. I saw what proto_wss can do but I did not understand it properly. it will send traces to a server i don't need. I just need it if a user is busy or idle. or he gets unregistered that's all. Thanks ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
[OpenSIPS-Users] Push notification for zoiper ios app
Hi, I am running opensips 3.2.6 and trying to test push notifications for my zoiper IOS app. I have enabled pn_enable and added pn_providers "apns, fcm, webpush, acme". I am not sure how to add the contact header with the pn stuff ? Is there any specific parameter with save() to enable it ? I don't have anything in the middle, just a zoiper ios client that is sending REGISTER requests to my opensips. I only want to send PN to specific devices. I did not find any example of how to handle the PN overall. Thank you ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
Re: [OpenSIPS-Users] Configuration
Hi Phil,
Easy thing, if your user is registered and he makes a call that will become
an outgoing call. Just send it to PSTN. You can simply use t_relay or use
the dispatcher module.
You only need uac_auth if your PSTN network somehow sends calls to your
opensips using SIP and trying to authenticate. is this the case?

Re: [OpenSIPS-Users] phone not getting regsitered using TLS
Hi Karsten, I thought the same initially but then looks like logs are saying: Client used ciphers are: TLS_RSA_WITH_RC4_128_MD5 TLS_RSA_WITH_RC4_128_SHA and servers response is cipherSuite TLS_RSA_WITH_RC4_128_SHA isn't it?

[OpenSIPS-Users] Wildcard domain certificate for tls
Hi Dear community members,
I have a few client domains for TLS. Is there any way I can use a wildcard
domain like *.mytestdomain.com and use that in the certificate? This way I
do not have to create a certificate for each domain.
My config works fine with single domain which i am using like this:
modparam("tls_mgm", "certificate",
"[sip.tls.xx.xx]/etc/letsencrypt/live/sip.tls.xx.xx/cert.pem")
I am using wolfssl as tls_library.
Opensips version is 3.3
Thank you.
