[asterisk-users] Yet another problem with incoming SIP calls and 407

[Wolfgang Zweimueller]

Hi all,

when I receive incoming SIP calls on my Asterisk (1.2.9.1) where the
caller has a username in it's From-Address which also exists in my
sip.conf then my system answers with "407 Proxy Authentication
Required". If it's nonexistent username then callin works fine!

It seems that this is a problem in the SIP implementation of Asterisk
and found a few hints on how to resolve this (allowguest=yes,
insecure=invite,port etc.). But none of them does help!

Can anyone suggest what I else could try?


Thanks,
Wolfgang
