[Blink] Serious VoIP problems whenever Blink is connected

[Adrian Georgescu]

Not related but good to know if you own those boxes.

Anyway the point is the Fritz Box intercepts all SIP and RTP traffic and does something with it. So I am not surprised that is miss behaving when SIP end-points do something that FritzBox does not expect and was not programmed properly for handling it.

Is a generic problem with any "SIP aware" intermediate equipment in the path that tries to 'fix things'.

Regards,
Adrian
