Hello,
I am using Kamailio as SIP register with asterisk integration describe from hire:
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb .
asterisk is listen on public ip: 2.3.4.5:5060
kamailio is listen on public ip: 1.2.3.4:5060
everything is working well except some software VoIP clients (like Yate) and CISCO phone
like Cisco-CP7940G/8.0 and the new one from Cisco series. I’m testing now with Yate client
and Cisco. They are register OK but when a call is made Kamailio is answer back with 407
Proxy Authentication Required. When I register Yate or Cisco to asterisk directly the call
is passing normaly. I was trying to manipulate kamailio.cfg and more specifically the
part:
#!ifdef WITH_ASTERISK
if (!auth_check("$fd", "sipusers", "1")) {
#!else
if (!auth_check("$fd", "subscriber", "1"))
{
#!endif
auth_challenge("$fd", "0");
exit;
If i commented out this part the call is passing, but I do not have auth anymore (everyone
can register)
Here is ngrep:

Hello,
it is asterisk that asks second time - kamailio is verifying the auth
ok, then forwards to asterisk which asks again for authentication. Read
the notes from the Asterisk Database section in the tuorial:
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb…
You should not set the secret in asterisk table, but use another column
to store the password.
Cheers,
Daniel
