Re: [OpenSIPStack] issue in forking proxy

[Joegen E. B. <jo...@op...>]

Hi Paolo,

I did not realize that you are using the Softphone module.  Although 
OpenSIPStack library itself supports forked INVITEs, the version of OPAL 
used in the softphone module doesn't.  So it doesn't surprise me that 
you encounter deadlocks in OPAL because it is not wired to handle 
multiple early dialog SDP offers .  The development of the OPAL module 
in OpenSIPStack has been frozen for quite a while and there isn't any 
clear indication right now that I or someone else could continue 
development in this area.   The only active development efforts right 
now is OpenSBC related.  I would suggest that you consider other active 
Open Source UA implementations such as PJSIP.
