Hi all,

I have install kamailio 4.2 latest version with presence module.

But I cant get contact status and send message.

This is my configure file:

#!KAMAILIO
#
# Kamailio (OpenSER) SIP Server v4.2 - default configuration script
# - web: http://www.kamailio.org
# - git: http://sip-router.org
#
# Direct your questions about this file to: <sr-users-cR8azDVoa3IcDhw6gZKtMWD2FQJk+8+***@public.gmane.org>

# - option for NAT SIP OPTIONS keepalives: WITH_NATSIPPING
#
# *** To enable PSTN gateway routing execute:
# - define WITH_PSTN
