I have a group of users configured as extensions in *.These users are registered with a SIP Proxy Server and can receive calls very well. The problem happens when any user tries to make an outbound call. The proxy replies with a "401 Unauthorized" and * don't try another INVITE including credentials.
Here is part of the content of sip.conf.
[general]
port = 5061
bindaddr = *.IP
context = invalidcalls
;This account is used for inbound and outbound calls
register => myuser:[EMAIL PROTECTED]/999
[mydomain]
type=peer
host=myproxy
context=sip
username=myuser
secret=mypass
fromuser=myuser
fromdomain=mydomain
[user1]
type=friend
host=dynamic
defaultip=default.IP
username=user1
secret=secret1
dtmfmode=rfc2833
context=users
callerid="User 1"
nat=yes
Here is part of the content of extensions.conf.
;This part is working fine
[sip]
exten => 999,1,Dial(SIP/user1,,tr)
[users]
exten => _8.,1,Dial,SIP/[EMAIL PROTECTED],tr
When I dial the number 812345 from my SIP Phone, this is the message sequence
Phone -> Asterisk: INVITE sip:[EMAIL PROTECTED] SIP/2.0
Asterisk -> Phone: SIP/2.0 407 Proxy Authentication Required
Phone -> Asterisk: ACK sip:[EMAIL PROTECTED] SIP/2.0
Phone -> Asterisk: INVITE sip:[EMAIL PROTECTED] SIP/2.0 (with authentication header)
Asterisk -> Phone: SIP/2.0 100 Trying
Asterisk -> Proxy: INVITE sip:[EMAIL PROTECTED] SIP/2.0
Proxy -> Asterisk: SIP/2.0 401 Unauthorized
Asterisk -> Proxy: ACK sip:[EMAIL PROTECTED] SIP/2.0
The next message I would expect is another INVITE from * to the proxy with the authentication header.
Why * hasn't send it? Can someone give me a help?
Thanks in advance
