[asterisk-users] Problem with OPTIONS requests.

Hey John,

In one installation I have, we use several monitoring tools (nagios based
and custom scripts based) and we have the following:

exten => s,1,Wait(1)
same => n,Hangup
: For Nagios
exten => nagios,1,Wait(1)
same => n,Hangup


1- We have context=public in sip.conf, if you have anything else, you must
update the dialplan above accordingly.
2- The second 'nagios' extension, is because the scripts need to send a
user, so we have it preconfigured to "nagios", if it's from Kamailio it
won't send a user and thus it will match in the s,1 exten. Feel free to
remove this one.

Give it a try and let me know how it goes.

Alternatively, you may also be able to configure your SBC
(kamailio/opensips? if so check dispatcher docs for *_reply_codes modparam)
to accept a 404 reply to a SIP:OPTIONS as a valid response.

Hope it helps.
