[pjsip] Using more than one ETH device

Hi Benny,

I've changed to 0.8.0 version. Now I can bind an account to a specific  
transport (in this case 2 different ethernet devices) but after  
checking with ethereal I noticed that rtp transport is binded to only  
one off the ethernet devices. I tried to create 2 rtp transports, one  
for each ethernet device but failed with this error:

  20:11:07.341  pjsua_media.c Unable to create RTP/RTCP socket: Cannot  
assign requested address [status=120099]

Is it possible to create 2 rtp transports with the same application?  
Thanks and best regards

Jorge Amador
