Hi, es hat mich etwas Zeit und Muehe gekostet, das GXP 1200 mit T-Online zum Funktionieren zu bewegen. Dank des VoIP Forums und Nutzer lango hat es schlussendlich geklappt. Hier meine Einstellungen: Account active: yes Account name: Telekom SIP Server: tel.t-online.de Outbound proxy: (leer) SIP User ID: (T-Online Telnr... 032xxxxxxxx) Authenticate ID: (bei mir der erste Teil der Emailadresse vorm @) Authenticate Password: (T-Online SIP Passwort) Name: (T-Online Telnr... 032xxxxxxxx) Use DNS Srv: Yes User ID is Phone Nr: No SIP Registration: Yes Unregister on Reboot: Yes Register Expiration: 15 local SIP Port: 5070 SIP Registration Failure Retry Wait Time: 20 SIP T1 Timeout: 1 sec SIP T2 Interval: 4 sec SIP Transport: UDP Use RFC3581 Symmetric Routing: No NAT Traversal (STUN): Yes Subscribe for MWI: No PUBLISH for Presence: No Proxy-Require: (leer) Voice Mail UserID: (leer) Send DTMF: via RTP (RFC2833) Early Dial: No Dial Plan Prefix: (leer) Delayed Call Forward Wait Time: 20 Enable Call Features: Yes Cal Log: Log all Calls Session Expiration: 180 Min-SE: 90 Caller Request-Timer: No Callee Request-Timer: No Force Timer: No UAC Specify Refresher: Omit UAS Specify Refresher: UAC Force INVITE: No Enable 100rel: No Account Ring Tone: system ring tone Send Anonymous: No Anonymous Method: Use From Header Anonymous Call Rejection: No Auto Answer: No Allow Auto Answer By Call-Info: No Turn off speaker on remote disconnect: No Check SIP User ID for INVITE: No Refer-To Use Target Contact: No Disable Multi Media Attribute in SDP: No Prefered Vocoder: 1.
