Hi,
hab ein SNOM 370 mit dem SNOM-Eigenen OpenVPN Client (tun) eingerichtet. Hab das Gerät auch von meinem Telearbeitsplatz aus probiert und es ging.
Nun hat der Mitarbeiter es mit zu sich genommen und er kann nicht intern telefonieren. Das einzige, was offensichtlich anders ist, ist die Internetanbindung. Die ist bei mir mit VDSL sehr gut, bei ihm SEHR schlecht mit einem ADSL Light, wo die Latenz häufig in Richtung 2 Sekunden geht. Der Apparat hat außerdem auch die BLF aktiv wo 15 andere Teilnehmer überwacht werden und als Telefonbuch wird LDAP verwendet. Vielleicht verursacht die SIP Überwachung ja auch zuviel Daten für die dünne Leitung...
Jedenfalls kann er nicht intern telefonieren jetzt und ich weiß aber nicht woran es liegt... Könnte es auch an der MTU liegen?
Hier die sip.conf
Hier mal ein sip debug log:
