Lancom als SBC
Dieser Artikel ist noch unvollständig!
Für Telekom-Trunks bietet es sich an, einen Lancom-Router als SBC zu betreiben.
Lancom-Konfiguration
Der Telekom-SIP-Trunk kann per Assistent eingerichtet werden.
Weiterhin muss im Call-Router eine eingehende Route für alle Anrufe (#) zur UCware und eine ausgehende Route zum Telekom-SIP-Trunk eingerichtet werden. Zusätzlich ist ein 1:1 SIP-Mapping von allen gewählten Rufnummern (#) auf # nötig.
Gateway-Konfiguration
In den erweiterten Einstellungen für das Gateway muss fromdomain = intern gesetzt werden.
Durchwahl übermitteln
Lancom-Router erwarten die Durchwahl als P-Preferred-Identity-Header. Dazu in der /etc/ucware/ucware.php Quirks aktivieren ($QUIRKS = true;) und die folgende Datei auf der Anlage anlegen.
- /etc/ucware/asterisk/quirks-enabled/lancom.lua
local Channel = require 'core.channel' local Log = require 'core.logger' local realm = "intern" --- Add the P-Preferred-Identity SIP header. -- @param self caller object -- @param extension callee extension -- @param gateway gateway object with the following fields, {type, grpId, id, allowOut, extsource, host, name, title, dailstring} return function(self, extension, gateway) -- get callerid from channel local callerid = Channel["CALLERID(num)"] or 'anonymous' app.sipremoveheader("P-Preferred-Identity") app.sipaddheader(("P-Preferred-Identity: <sip:%s@%s>"):format(callerid, realm)) end
Troubleshooting
- Registrierung wird mit 401 Unauthorized abgelehnt: Im Voice Call Manager des Lancom-Routers Lokale Authentifizierung erzwingen deaktivieren
Beispielkonfiguration
Das folgende Lancom-Konfigurationsskript kann als Basis für eine eigene Konfiguration genutzt werden.
