Yes, I can confirm upgrading asterisk from 1:13.13.1~dfsg-4 to
1:13.14.0~dfsg-1~exp1 fixes the issue.

Bug#853792: res_rtp_asterisk.c: Unable to allocate RTP socket: Address family not supported by protocol

[Grzegorz Ojrzanowski]

Package: asterisk
Version: 1:13.13.1~dfsg-2
Severity: important
Tags: upstream

After upgrading asterisk (1:13.12.2~dfsg-2 => 1:13.13.1~dfsg-2) I wasn't
able to make calls anymore, the message displayed by Linphone was
'Not acceptable here' and the following error was logged on asterisk host:

[2017-02-01 08:26:01] WARNING[1600] res_rtp_asterisk.c: Unable to allocate RTP 
socket: Address family not supported by protocol
[2017-02-01 08:26:01] WARNING[1600] res_rtp_asterisk.c: Failed to create a new 
socket for RTP instance '0x7fcea4049f30'
[2017-02-01 08:26:01] ERROR[1600] res_pjsip_sdp_rtp.c: Unable to create RTP 
instance using RTP engine 'asterisk'

Because I have IPv6 disabled (in /etc/defaults/grub using:
GRUB_CMDLINE_LINUX="ipv6.disable=1") this was my first suspect which
google soon confirmed.

A bug was introduced in Asterisk 13.13.0 which was reported in
https://issues.asterisk.org/jira/browse/ASTERISK-26617
and the fix will be included in next (13.13.2) asterisk release.

Until then, IPv6 needs to be enabled or Asterisk version 13.12.x used
instead
