Subject: Re: [Users] nathelper & fax = bug ?
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
