"The best business telephones in the world."

Eine Kombination aus 2x M700 und 5 Handsets mit Asterisk funktioniert immer für einige Tage, danach hängt ein M700 SIP-seitig, über dass sich aber alle Handsets einbuchen wollen. Die LED des M700 blinkt dabei manchmal rot.

Die TLS-Verbindung zum Asterisk Server besteht, allerdings fließt hier kein einziges Byte an Daten:

tcp6       0      0 10.1.10.1:5061          10.1.10.6:52642         ESTABLISHED

Symptomatisch ist auch, dass nach einiger Zeit die DECT-Handsets mit immer größerer Verzögerung klingeln und bei hinreichend großer Verzögerung auch nie mehr aufhören zu klingeln, es sei denn, man weist den schon längst nicht mehr existieren Anruf am Handset ab (muss an jedem Handset durchgeführt werden).

Ich vermute hier mal ein Firmware-Problem in Form eines Resource-Leak (Memory, Handles, ...).

PBX is Asterisk 11.

As for certificates there's the PBX certificate and the associated internal CA Certificate but no client certificates.
