[OpenSIPS-Users] Opensips b2b scenario timeout

Hi again,

I think I have answered my own question; I discovered a XML subnode of 
the bridge element called "lifetime", the only information I can find on 
the XML is from a tutorial not from the module documentation.  I had 
assumed that this "lifetime" was a mechanism to terminate a call or 
media session after a specific amount of time, but it would seem that 
this does control the invite timeout, at least for the REFER scenario.

Many thanks,
