Hi,

I would like to request permission to update Asterisk in Stretch to a new
upstream release (13.13.2 to 13.14.0). This version has mostly bugfixes 
but only very minor new features.

Unfortunately a couple of bugs have surfaced that make Asterisk in Stretch
close to unusable in certain configurations. They are priority important right
now but are borderline RC for some system configurations

Bug#853792: Asterisk does not work at all on systems without IPv6. Only viable
	workaround is to enable IPv6

Bug#855014: The chan_pjsip driver has a broken codec selection that leads
	to asymetric codecs being negotiated with the endpoint, leading to
	one-way audio. The only viable workaround is to limit codecs on the
	phone to just one codec.

Both commits could be backported, but this would make it harder to support
during the lifetime of Stretch. Additionally there are a tons of other fixes
in this version that sound good-to-have in Stretch (memory leaks etc.). 

Additionally it would allow us to drop two patches that have been included
upstream and our OpenSSL 1.1.0 support would be much closer to upstream (we
cannot drop all patches because something is still missing, but all remaining
patches are already queued in upstreams CI for merging). 

There are no changes in packaging besides debian/patches.

The package is currently in experimental as asterisk/1:13.14.0~dfsg-1~exp1.
I'm asking for approval for upload to unstable. 

Bernhard
