RE: T38G Not Sending a BYE - Freeswitch
I discovered the issue. I factory-reset as promised and manually provisioned phone.

1. As a test, I provisioned the phone with transport UDP and created a DNS A-record for one of my servers. I put that in the outbound proxy, enabled the outbound proxy, and saved. The phone properly signaled the BYE upon termination of the test call.
2. I set the phone back to my transport that I was using in my provisioning files - (DNS-SRV) and put my SRV record back in as the outbound proxy. I then made the same test call and confirmed that the phone did not signal a BYE.

So based on this testing, I have concluded there is a bug in the firmware for proper RFC SIP Signaling if the transport is set to DNS-SRV. If you need any additional files or pcaps, please let me know and i'll happily create some and upload.
