HI,
I am still very new to this technology. All this lab is on an internal LAN.
X-Lite Software Telephone - 172.16.130.106 Cisco Fast Ethernet - 172.16.130.248 Cisco BRI connected to the ISDN Line Simulator with numbers 384001 and
384002.I've seen and searched for several scenario's etc. I have a doubt as some articles quote that I should use a SIP Proxy as well (like OnDo Sip Proxy) and some quote that the cisco router can do all the routing /authentication.
Any Idea from where to start such project? Up to now all i managed to do is configure the router (2821) lines etc, but i dont know what i should do more regarding VoIP, authentication and all the rest. Does anyone know of any article/tips or whatever that can help me?
Below is part of the router configuration related to VoIP.
Note: in this particular scenario I was trying to work with a SIP proxy, but still nothing is working and I am not sure if this is the correct way I am working.
