[Opalvoip-devel] Bad Gateway 502 - Fritzbox

[Michael P. <mic...@my...>]

  

I try to understand why this error happens in conjunction with the
Frizbox. OpalVoip is registered at Fritzbox and everything works fine
except this error 502 Bad Gateway. After a CANCEL from Fritzbox (call
completed elsewere) OpalVoip sends this error. We are using
opalvoip-3.14.3 running on an embedded device and we cannot update
easily. I try only to understand if this error is malconfiguration, is
caused by Fritzbox or is a opalvoip lib error.
