Hello,
is the SIP trace complete?
What I could find inside is:
- invite from phone to kamailio
- kamailio asks for authentication - 407
- ack
- invite with credentials, kamailio forwards to asterisk
- asterisk asks for authentication - 401
- ack
- there is no new INVITE with credentials for kamailio and asterisk
- but the phone starts sending CANCELs -- since there is no active
INVITE transaction, kamailio just drops it due to config rules
- after a while asterisk starts sending like 180 ringing, then 200ok ...
really strange
Maybe you haven't captured all the sip traffic. If you want to use
ngrep, do on kamailio server:
ngrep -d any -qt -W byline port 5060
If that's all the traffic, then xlite and asterisk seems to have some
bugs - both were aware of 401 reply (asterisk generated it, xlite sent
the ACK for it) -- so no ongoing call to CANCEL by xlite, or to answer
by Asterisk (the 180, 200 replies).
From kamailio point of view, if there is no INVITE following the 401
reply to xlite, there is no active invite transaction to cancel.
Cheers,
Daniel

Hello,<br>
<br>
I will look over it soon - since you sent pcap I couldn't look at
it directly from the email. ngrep outputs plain text which is easy
to read from email, the reason I am asking mainly for ngrep traces
since many times I am not around a computer where is convenient to
open pcap file. On the other hand, if it is a transmission problem
(at transport layer), pcap file is better.<br>
