Hallo alle miteinander,

möchte mit Kamailio und mit hilfe von RTPproxy eine Übersetung von IPv4 <---> IPv6 und umgekehrt erreichen. Es gab bisher leider nicht allzuviel über dieses Thema im Internet zu finden, bis auf eine Konfigurationsdatei die mit Kamailio ausgeliefert wurde und schon recht alt ist. Nach einigen Anpassungen von meiner Seite sieht diese wie folgt aus, doch startet der kamailio dann nicht, obwohl ein kamailio -c (check) keine Fehler meldet. Sieht wer den Fehler oder kann mir jemand einen Tipp geben ?

Den rtpproxy hatte ich zuvor so gestartet:
Code:
rtpproxy -F -l 192.168.1.11 -6 /fec0:a::1
Code:
#!KAMAILIO
#
# $Id$
#
# Kamailio (OpenSER) SIP Server v3.0 - basic configuration script
#     - web: http://www.kamailio.org
#     - git: http://sip-router.org

#
# Several features can be enabled using '#!define WITH_FEATURE' directives:
#
# *** To run in debug mode: 
#     - define WITH_DEBUG
#
# *** To enable mysql: 
#!define WITH_MYSQL
#
# *** To enable authentication execute:
#     - enable mysql
#     - define WITH_AUTH
#     - add users using 'kamctl'
#
# *** To enable persistent user location execute:
#     - enable mysql
#!define WITH_USRLOCDB
#
# *** To enable presence server execute:
#     - enable mysql
#     - define WITH_PRESENCE
#
# *** To enable nat traversal execute:
#!define WITH_NAT
#     - install RTPProxy: http://www.rtpproxy.org
#     - start RTPProxy:
#        rtpproxy -l _your_public_ip_ -s udp:localhost:7722
#
# *** To enable PSTN gateway routing execute:
#     - define WITH_PSTN
#     - set the value of pstn.gw_ip
#     - check route[PSTN] for regexp routing condition
#
# *** To enhance accounting execute:
#     - enable mysql
#     - define WITH_ACCDB
#     - add following columns to database
#!ifdef ACCDB_COMMENT
  ALTER TABLE acc ADD COLUMN src_user VARCHAR(64) NOT NULL DEFAULT '';
