Silence on B-Leg, busy tone on A-leg followed by registration fail
We have Freeswitch 1.4.21 x64 and a couple of Yealink T19P,T22,T26P and single T42,T46.
Recently something strange is happening with phones.
Absolutely randomly theres a silence after pickup on callee side and busy tone on the caller side.
Freeswitch log shows NORMAL_TEMPORARY_FAILURE and nothing more.
Immediatly after that the callee phone reports "Registration failed" and starts re-registration which ends successfully. Shortly after re-registration all calls are working normally without any failures.
This issue appears randomly on all our IP-Phones and somehow only on TLS-registered.
Phones registered by UDP are not affected.
Trusted certificates validation is turned off.

Here is a part of T22 syslog from receiving call to hangup.
Could anyone help me with log understanding?
