Asterisk registriert an SIP Trunk: outbound nichtdeterministisch rejected/forbidden oder network out of order
6 years ago
Wir betreiben seit Wochen einen SIP-Trunk (chan_sip) an freePBX mit Asterisk 13. Die Kollegen melden sporadisch Probleme beim Raustelefonieren. Angeblich seinen keine Leitungen verfügbar. Nach Prüfung des Log-Files fiel auf, dass wir das Problem täglich haben. Heute trat das Problem bis 16:06 bereits 30 Mal auf. Ich habe entsprechende Log-Meldungen nach Häufigkeit sortiert:
17x HANGUPCAUSE = 21 - rejected/forbidden
