Zulu Originate Call hangs up on both the caller and the outgoing call

Using the following:
Zulu Windows Client 2.0.0 (same result using 1.0.0 client)

When using the originate call feature, the desktop phone rings, then when I answer it hangs up on me. Then, the outgoing call is made, and as soon as that phone is answered, the system hangs up that line as well. Any suggestions would be appreciated. Thank you.
