[asterisk-users] Asterisk 11.10.2 update breaks snom TLS transport

I've recently updated an Asterisk installation to 11.10.2 (from the
Gentoo packaged build), and the update has (seemingly) broken TLS
transport for snom phones (I could reproduce on snom 3x0 and 7x0 with
8.4.3x and 8.7.x.y firmwares). What happens is that the registration to
the PBX is successful, and inbound calls work normally (i.e., when the
phone is being signalled that a call is coming in), but dispatching a
call from the snom phone to the PBX makes the TLS transport "hang"
(i.e., the PBX doesn't see any more TLS packets from the phone, and
OPTIONS is no longer replied to). The phone then kills the TLS channel
after a while (probably times it out) and Asterisk marks the phone as
unreachable due to QUALIFY, and after some time (roundabout two minutes)
the phone reconnects the TLS channel and is reachable again. I couldn't
reproduce this behaviour with other phones (i.e., Gigaset devices which
I also use with TLS transport).
Is this a known regression, and generally: how can I help diagnose this
problem further for opening a bug-report, besides the description given
above? Has anyone else encountered this and found another workaround
besides switching to TCP/UDP-transport for the phones?
Thanks for any hints in advance!
