[SR-Users] Kamailio -PSTN Gateway

[Zaka Ul Isam]

Hello Folks:

Please help with above, I have browsed and tried various suggestions on this list without much luck!

I think problem can be reduced to three questions ;)

1: Apart from DEFINE WITH PSTN directive, do I need certain modules to be compiled? (DIALPLAN, CARRIERROUTE, LCR aso) If yes, then we ought to put up a list of modules required for each task/ activity.....

2: How Kamailio core decides the call routing? i.e: based on dialed digits as specified in dialplan .

# - update the condition to match your dialing rules for PSTN routing
if(!($rU=~"^(\+|00355)[0][4-9]{3,20}$"))
return;

&&

#!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 = "10.1.6" desc "PSTN GW Address"
pstn.gw_port = "5080" desc "PSTN GW Port"
#!endif


3: If Kamailio is listening on say wlan0 interface 10.42.0.1:5060 (Ubuntu HOT SPOT) can it route to PSTN Gateway/ Softswitch on P2P1 (Eth0) without Bridging? Put another way, does kernel route towards the specified interface or Kamailio is capable of routing based on active routing cache?

Thanking you in advance,


Zak

if you have only a pstn gateway, it is not necessary to add extra modules.

If you have more, makes sense to get lcr or an alternative, the right
place with be to replace some of the content in route PSTN with
functions from the new module.

Yes, in the case of default config file, but you can change that as
needed by you. Default config file was made mainly to give an example of
routing to PSTN, but can be update to match your rules for sending to PSTN.

This is a matter of your routing rules in kernel. Also, if you do
natting there, the PSTN gateway must be able to do nat traversal for rtp.

Morning Daniel:

Thank you very much for your response!
As for the routing explanation, I am afraid, I couldn't narrate the issue. I rephrase it, here below:

1: By default Kamailio listens on all interfaces (implying that it has knowledge of all interfaces and corresponding subnets, please correct me if wrong.
2: A packet arriving at say 10.10.10.1/8 will be processed by the corresponding module....
3: A packet destined for 192.168..1.15/24 (say our PSTN GW/ MGC) how will it be routed? Wil it be sent on all interfaces wlan0 (above) and eth0 with same subnet as eth0 or only sent out via eth0?

Thanks again!

KR,

Zaka
