I believe you're right, when sending packets from the application after the error is seen, the error is seen again. However it still functions. Maybe one out of my four packets is bad.

You're right, from my research so fair, it seems that the Call Manager tells the phone exactly what to do. This seems intimidating to support myself; perhaps I'll try to find software with an API that I can interface to.

Looks like I have plenty of research to do. Thank you for giving me a good foundation to continue with.

@Ale Ok, I reset everything and I found that SYN packet. The phone initializes the connection.

@Ale This makes sense, I do see "Source port" as 2000 in Wireshark.

@Zoredache Thank you for your insight; I gave TeraTerm a try and it gives a connection time out. It probably explains why PuTTY is closing.

I tried PuTTY again with 49922 as the port and it still crashes.

Now that I take a closer look, Wireshark says the destination port is 49922, which I assume would be for the phone. Also, packets to the phone are "SKINNY" protocol, whereas returning packets are TCP.
