30 seconds calls are usually an ACK problem due to NAT. Make sure the callee receives the ACK.

Only B2BUA can generate a BYE, so it's definitely not SER. However, there may be something else that causes Vovida to generate it. I would start in that end. I don't know Vovida, so I wouldn't know where to start... g-)

Does anybody have SER running with MEDIAPROXY and Vovida B2BUA at the same machine?
I'm having a little trouble with the calls: They are finishing after 30 seconds.
After I have reviewed the NGREP sniffing I can detect that the B2BUA is sending a BYE to the SER as you can see:

Does anybody know if this is a problem with the VOVIDA B2BUA or the SER? Any idea?
