Hi Rizwan,

that is the right approach .

For adding an Asterisk as SBC you can use the section route[PSTN] at kamailio.cfg

#!ifdef WITH_PSTN
# PSTN GW Routing
#
# - pstn.gw_ip: valid IP or hostname as string value, example:
# pstn.gw_ip = "10.0.0.101" desc "My PSTN GW Address"
#
# - by default is empty to avoid misrouting
pstn.gw_ip = "IP_OF_YOUR_ASTERISK"
pstn.gw_port = "5060"
#!endif

Make kamailio IP as trusted IP in your asterisk sip.conf like

[kamailio]
type=friend
context=outgoing-kamailio
host=[IP_OF_YOUR_KAMAILIO]
port=5060
qualify=no
;trustrpid=yes
;sendrpid=yes
deny=0.0.0.0/0.0.0.0
permit=[IP_OF_YOUR_KAMAILIO]

add outgoing trunk Data to your asterisk sip.conf and extensions.conf section [outgoing-kamailio]

and that is it.

Regards
Rainer

Is my question not well phrased? Or is too general? Can anyone help with a document or an older thread which could help me?

Thanks

I want the following setup:

1 Kamailio server to handle internal calls (A/V), IM and Presence.

1 Asterisk or any other way to communicate with an NGN where I will create the SIP Trunk to route calls outside of the network.

Is this the right approach or there is a way to directly communicate with the NGN to make a SIP trunk by using some external modules.

Any guidelines will be highly appreciated.
