[asterisk-users] Handle Options Method

[Thomas Deillon]

Hi,

 

I have an Alteon in test (a sip/rtp load balancer).

This Alteon sends to the asterisk box a "SIP OPTIONS" to know if
asterisk is alive. 

However, asterisk sends me a 404 message and not a response like, for
example, a Thomson (200 + SDP)

 

I wrote a very little script (you can find it at the end of the email)
to send an Options message to asterisk/phones to try.

It works like this: ./Options.py eth0 192.168.1.35(ip of the UA) 

 

Do you know why asterisk send me a 404 message and how can I ask him to
answer correctly?

 

Thanks a lot for your help,

 

Thomas
