Hello,

please send me your config file. It seems that is a bit different than 
the one on voip-info.org. The re-INVITE is managed via nathelper, but 
the force_rtp_proxy() is called twice, the re-invite sent by openser 
contains:

c=IN IP4 192.168.39.54192.168.39.54 and a=nortpproxy:yes..a=nortpproxy:yes..

This is a bug in the configuration file.

Cheers,
Daniel
