| * Your ''debian.org'' email address is also your SIP address
* E.g. ''firstname.lastname@example.org''
* Your SIP software may try to use the user-part of the SIP address for authentication. It will not work.
* In your SIP settings, look for an ''authentication username'' or ''auth user'' field. It is often blank by default.
* Put your full SIP address, e.g. ''email@example.com'' in this field
* The same credentials are used for TURN
* If you are lucky, your client software uses DNS NAPTR and SRV lookups to find the TURN and SIP servers, if not, you can hardcode the following values into your configuration:
* SIP server: please use a client that finds it using SRV lookups
* if really necessary, use the value ''vogler.debian.org'' and TLS, port 5061
/!\ Don't do that. We don't want to couple service names with hosts names! -- zobel
* TURN server: ''turn.debian.org'' (UDP port 3478)
* SIP over WebSocket: ''sip-ws.debian.org'' (HTTP port 443)

|== NAT traversal ==
* NAT and firewalls have traditionally been a problem for free RTC software
* For SIP itself, we only use TLS
* This is a stream connection that is more likely to get through NAT than UDP
* It can also potentially be tunnelled through proxies using the HTTP CONNECT method (port 443)
* Some routers try to mangle SIP packets to help them through NAT, in practice this sometimes makes the problem worse
* By using TLS, we ensure that no intermediate device will tamper with the packets, we aim to use industry standard ICE and TURN
* The modern approach to this problem is the use of Internet Connectivity Establishment (ICE) and, as a last resort, relaying traffic through a TURN server
* Not all SIP clients support TURN
* Jitsi only supports TURN with Jabber, the SIP-TURN support is coming
* Empathy only supports TURN through Google's proprietary TURN servers, but the TURN code could use any TURN server if configuration options were available. There is a bug report for this.
* Only one end of the connection needs a TURN server for it to work though, as long as both support ICE.
* The [[https://rtc.debian.org|rtc.debian.org]] WebRTC service is based on [[http://jscommunicator.org|JSCommunicator]]. It supports both ICE and TURN and is pre-configured for Debian's TURN servers. Although the UI is very basic, there is a high probability that it can get through NAT in situations where the other SIP clients currently struggle.
== WebRTC status ==
* [[http://www.webrtc.org/|WebRTC]] users can only interact with other WebRTC users
* Jitsi and Lumicall users can interact with each other but not with WebRTC users (yet)
* People who don't have a SIP account can call you instantly using the [[https://freephonebox.net|FreePhoneBox.net WebRTC service]]

SIP (Session Initiation Protocol) Proxy, allowing to pass VoIP phone calls. decommissioned (https://alioth-lists.debian.net/pipermail/debian-rtc-team/2020-May/000194.html)
TURN (Traversal Using Relays around NAT) server. decommissioned (https://alioth-lists.debian.net/pipermail/debian-rtc-team/2020-May/000194.html)
- XMPP/Jabber server
- The following services are NOT available yet but are being planned or under consideration
- BOSH Support, to connect to the XMPP server over HTTPS
You must create a real-time communications (RTC) password in the LDAP system: login to update your settings, then fill the RTC password field.
- Do not use the same password that you use for any other Debian service. For example, you may want to cache the RTC password in a mobile device where there is a risk that it will be compromised, exposing the password.
- Wait 30 minutes for the password to become active.
Your debian.org email address is also your XMPP address
