New subject: [Serusers] NatHelper Bug w/fix_nated_sdp("2")

27 Nov 2003

Hi Jan,
I came accross this problem too with 0.8.12. 
fix_nated_sdp("3") instead of replacing the value of "c", SER appends
the ip address to the existing value - something like - 

c=IN IP4 162.33.165.196162.33.165.197

and kphone crashes while trying to resolve this.

I registered your first mail, but I didn't have enough time to take a
look at it yet.

 if you look at the statement capture below you will see "c=IN IP4
 162.33.165.196162.33.165.197.."
 you can see that it has appended the ip address and not replaced it. it
 should read
 c=IN IP4 162.33.165.197..

 the statement that causes this is fix_nated_sdp("2"); which is supposed to
 rewrite the sdp ip I believe.

 Thanks
