[OpenSIPS-Users] sending sip options

[Arsen]

Hi Michel,

Proxy server never generates OPTIONS requests, do you use a probing like in
mod dispatcher (ds_ping_method) ?

"400 Bad Request" indicates that the request was not understood by the
server, it could be due to missing of the required header for example, but
in your case the request has all required headers.. maybe the issue is on
the remote side..

Regards,

Arsen Semionov
