[Blink] Blink Pro calls hang up after 4-5 seconds

[Kevin Layer]

I saw a message about "remote end hung up" but they didn't and
Telephone works perfectly.  It happens 4 or 5 times.  So, I switched
to Telephone, since I needed to talk to people.

I just switched back and Blink Pro is working.

Next time this happens, other than sending the Activity and SIP lots,
what can I collect that will help chase down this problem?

Thanks.
