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

Typically this is a signalling problem so the SIP trace would be enough.

Both Telephone and Blink use the same SIP stack (that is PJSIP). But they both employ deferent default codec list and settings. If one works and the other doesn't, it could be caused by the use of different transports (like UDP versus TCP or TLS), codecs list or options like encryption or usage of STUN and ICE protocols.

Another helper would be to use the built-in SIP accounts from within Blink. They use sip2sip.info service, which is pretty reliable. If it works with sip2sip, we can can eliminate some of probable causes.
