Please provide a 'Transparent Header' or 'Wildcard Header' support option #52
Description
Hi
When acting as a B2BUA for example between a kamailio routing core and a kamailio registrar node usually informations are passed to the registrar as custom sip headers. Like X-VM: yes to tell the registrar that the customer has voicemail enabled so the registrar can forward the call to voicemail if needed.
So it would be very handy to have sippy pass on all 'unknown' header as is. Or at least to be able to define some regex matcht header like X-.* which would be passed transparently on the 2nd leg.
