[Asterisk-Users] Problem Making a SIP call over a long latency network - Call rejected: 407 Proxy Authentication Required

[aram]

Hello,

We are getting error: Call rejected: 407 Proxy Authentication Required - if
a user is trying to call using * over a long latency network (around 600
ms).  There is no problem when the same user is trying to make a call with
low latency network (around 300 ms).  I have included the debug and log
messages for Asterisk.  This call is done with SJphone, the same problem
exists with ATA; however X-Pro is having no problem.  Similarly if the user
is not authenticated - the call goes through fine. 

            Is * timing out waiting for some response - if so how can we
increase the timeout?  We are also thinking of possibility that some port is
closed over the long latency network that causing this problem - is that
possible -if yes, which port would that be?

            Or is there another issue that we are not aware of?

 

            Thanks,

            Aram
