Brandon,

Thank you again for assisting me with this issue and providing me direction. I began logging my SIP traffic and, when this issue occurs, VOIPo sends three INVITES and my BYOD device takes 15 or more seconds to respond. I believe I have traced this down to a new Wi-Fi “optimization” feature that was introduced a few months ago with a software update for my BYOD. Since disabling this feature, I have not been able to reproduce the issue and call reception works as expected.

If something should change here in the future, I’ll update the thread.

Cheers.
