Folks:
Every now and then I look at our public SIP server's log files. I have come
across INVITE SIP requests that do not have the userinfo field in the
Request URI. As far as I know, while the userinfo field is prohibited in
the REGISTER request, it is mandatory in the INVITE/OPTIONS/BYE/ACK
requests.
In other words, while
REGISTER sip:lucent.com SIP/2.0
is fine,
INVITE sip:lucent.com SIP/2.0
is not; the userinfo field is required:
INVITE sip:[EMAIL PROTECTED] SIP/2.0
Thanks,
- vijay
