Aborting call on unexpected message error

[vijayaa]

i am testing the following scenario with freeswitch

source: 172.31.0.23
destination: 172.31.0.26
max_concurrent: 1
calls_per_second: 1
number_of_calls: 1
from_user: 1000
to_user: 1001
steps:

• invite
• wait_for_answer
• ack_answer
• sleep 10
• hangup

Getting the following error.
Aborting call on unexpected message for Call-Id '1-3332@172.31.0.23': while expecting '180' (index 2), received 'SIP/2.0 407 Proxy Authentication Required

Could you please tell what is the issue

Pretty simple. Looks like your placing a call to a server that is requiring authentication on the call. Not sure how to inject WWW digest authentication, but maybe the devs can help. :)
