[Freeswitch-dev] OPTIONS

[Suneel Papineni]

Thanks Anthony, as you said it is a violation of SIP specs. I will try
and see if your alternative suggestion works with my set-up.

You cant block options but you can block new invites with "fsctl pause"
That would cause the calls to fail over to the2nd route at least until
the current calls are over.
That is the only solution there is no way to not reply to options and
there is nothing we can do to make that possible as it's a violation of
the SIP spec.  you would have to use a sip router like openser for that.

Thanks Bret, but unfortunately I didn't have control on Gateway because
it is a 3rd party (Except for adding primary and secondary FS IP
addresses). So I need to do something at FS end only.

I would think that adding code to do that would cause some breakage.
The better solution would be to have a trigger on your gateway to tell
it to fail all calls over.

If you did an ACL or packet filter or anything else, important messages
may be lost.  The exception would be if it does OPTIONS to a different
port and you block that port only, so normal sip traffic goes through
but the ping is stopped.  This would be to a 2nd profile but the same
instance of freeswitch, so it should work the same in terms of
availability.

You could modify sofia so that it could block this, but I do not think
that it would be committed as a result you would have to maintain this
out of tree.  I could be wrong, it might get committed, but given that
there are other solutions, and this one has some potential to create
headaches for others I do not believe that it would.
