Hi again!

Thanks for your hint. I tried it, of course:-) But asterisk still tries to
create a new, additional connection to the endpoint. I verify this with a
tcpdump session.
Endpoint/AOR config:

[12300001_3]
type=aor
max_contacts=1

[12300001_3]
type=endpoint
transport=
context=test
disallow=all
allow=alaw
allow=gsm
media_encryption=sdes
rtp_symmetric=true
force_rport=true
ice_support=true
direct_media=false
send_pai=true
auth=12300001_3
aors=12300001_3

After reloading I see with pjsip show endpoint:
...
  tos_video                     : 0
  transport                     :
...

Seems to be correct ;-)

I have 3 transports configured, 2 udp, 1 tls. I also saw this while debugging:
<--- Received SIP request (1112 bytes) from TLS:192.168.203.81:44160 --->
.....
Contact: "A. Valentin" <sip:12300001_3 at 192.168.203.81:58251;transport=TLS;ob>;+sip.ice;reg-id=1;+sip.instance="<urn:uuid:00000000-0000-00

Look at the port, both ip's are in the same subnet. But this shouldn't make a difference since I use force_rport=true, or not ?

Do you have any idea ? I'd love to switch to pjsip and gain more experience :-)

Kind regards,

André
