I would like to use a softphone on my desktop. We have an telekom IP contract and they tell me it is possible to use any sip phone. I installed SFLPhone and tried to enter my credentials but it just fails.
I asked my provider, they told me the following:
SIP-ID/Benutzer: Ihre Telefonnummer
Bildschirmname (falls vorhanden): Ihre Telefonnummer
Authentifizierungs-Name / Benutzername: Ihre E-Mail-Adresse, z.B. "[email protected]"
Passwort: Ihr Passwort
SIP-Proxy: tel.t-online.de
Registrar: tel.t-online.de
Realm: tel.t-online.de
STUN-Server: stun.t-online.de
Outbound-Proxy: leer lassen oder ebenfalls tel.t-online.de
I tried nearly every combination but I can't get connected. But I don't see why. I don't know where to put what.
Does somebody know how to debug sflphone (or other softphone on ubuntu) to see what fails exactly?
(or even better: does somebody know how to configure it with telekom IP contract?)
You can try Ekiga instead. It has less options and probably will solve your issue.
You will only need to write your Registrar (tel.t-online.de), username, and password.
If it does not connect then try setting STUN or Proxy in Preferences.
