Yes I had already thought about making some development on the top of the dialog module but I was hopping that somebody else pointed me to an "easier" solution. The use of sst module sounds good too. I guess I will give a try to both suggestions and then I will decide which one is the best for me.

another option is to place a b2bua in the middle (like 
asterisk/freeswitch). Probably the architecture get a bit more complex 
in this case, but if you need some media processing (e.g., transcoding) 
you just combine them.

Cheers,
Daniel
