[Linphone-users] Client Content Length mis-match.

[Jeremy Whiting]

Hi,
 My Linphone client was working well up until a few weeks ago.

 When I attempt to establish a call the client reports this message with red  color text
 
"Content-Length mis-match 00:00:00"

 but the connection with my VOIP provider is then closed.

 The debug log reports this trace

message: Call 0x2985530: moving from state LinphoneCallOutgoingProgress to LinphoneCallError

 I contacted my VOIP provider. They looked at the call logs and the back end systems did log the fact my client connected.
 I have tried various numbers in my contact list that used to work. So it isn't that.

 Looking at the trace I see there is Content-Length: initially 376 followed by 0 then 0. Should I be expecting a content length greater than 0 ?


 My system is running Fedora 22.

Regards,
Jeremy
