Runtime error on Debian Jessie: UDPPacket (NameError)

[ghost]

I'm getting the error sippy_cup/media.rb:117:innew_packet': uninitialized constant PacketFu::UDPPacket (NameError)` when running sippy_cup on Debian 8.6, Ruby 2.1.5 installed via apt-get. I'm using a basic sippy_cup file and running sippy_cup as root. This is my first time attempting to use this software. Please advise for user error if that's the root cause.

It looks like the last version of packetfu isn't compatible with sippy_cup. Adding gem 'packetfu', '1.1.11' into Gemfile resolves the issue.

@bklang you can close this issue as you've resolved it in #90

Thanks @gemasergey for reporting it and @leifmadsen for the fix!
