I have the following problem

When trying to setup asterisk 13.1 with PJSIP to connect to my IPV6 capable
SIP provider the registration fails.

For my naive eyes it looks as if there is no ipv6 name resolution (a DNS
AAAA query) performed.

Here are the (relevant) entries in the configuration files:

pjsip.conf
[code][udp-ipv6]
type=transport
protocol=udp
bind=[2a02:8070:86c0:2ca0:ba27:ebff:feda:bbb6]:5060

...

[endpoint-ipv6](!)
type=endpoint
context=ExternalSets
transport=udp-ipv6
rtp_ipv6=yes
disallow=all
;allow=g722
allow=alaw
allow=gsm
allow=g726
allow=ulaw

[registration-ipv6](!)
type=registration
transport=udp-ipv6
;auth_rejection_permanent=no
retry_interval=60

[easybell](registration-ipv6)
outbound_auth=easybell
server_uri=sip:sip1.easybell.de:5060
client_uri=sip:<userid>@sip1.easybell.de:5060

[easybell](endpoint-ipv6)
;context=ExternalSets
outbound_auth=easybell
aors=easybell[/code]

The own IPV6 address is recognized:

[code][Dec 22 19:24:14] DEBUG[25222] pjsip:      udpv60x998200 SIP UDP IPv6

The IP address of the partner is recognized:

[2001:4090:4008::124]:0/[ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff]:0 sense 0
appended to ACL[/code]

The problem is when Asterisk tries to [b]register[/b] with the other host.

Anyone have an idea what is wrong or missing, I am appreciating any hint.

Thank you in advance!
