[Freeswitch-dev] bad REGISTER processing

Thu Apr 10 14:42:47 EDT 2008

Hi all,
I'm back and the bug too :-)

Now I try to setup NAT handling:

<variable name='sip-force-contact' value='NDLB-connectile-dysfunction'/>

and FreeSWITCH starts to rewrite contact (append port 5060) like in 
previous case...

Best regards,

kokoska.rokoska
