Good day.
In logs you've sent we see 2 tries to establish a SIP call:
1. Your first call was not established because you probably set wrong authentication parameters, here's SIP signaling sequence from server log:
Code:
--------------------> INVITE sip:callee@domain SIP/2.0
<-------------------- SIP/2.0 407 Proxy Authentication Required
--------------------> ACK sip:callee@domain SIP/2.0
--------------------> INVITE sip:callee@domain SIP/2.0 with digest authentication data
<-------------------- SIP/2.0 403 Forbidden
2. Your second call was not established because you set wrong callee: SIP login like "callee@domain" is not allowed.
So you should check your SIP authentication data.
