I am learning Protocols where I have major use of Media Gateway Controllers, Media Gateway, PSTN N/w, VOIP N/w. Calls getting gatewayed from one node to another.

Kindly help me in finding out some related software simulators where I can view pictorially the messages being exchanged between the various nodes in telecom architecture.

Thanks

Wireshark is as good as you're going to get without spending a huge sum of money.

Just WireShark would work not at all for SS/ and ISDN, you know. –  TomTom Jun 17 '11 at 5:38
    
@TomTom: hum, do you know sigtran ? it's basically PSTN signalling protocols over IP, including SS7. Wireshark is able to decode it. –  petrus Jun 17 '11 at 10:04

You can setup a voip lab using software ipbx, like running Cisco Call Manager as virtual machine.

I know that it's possible to run it in VMWare with version 6 and 6.1. It may be possible with others (7+).

If you have the necessary licence/contact/money, you may also run an Alcatel Appliance, which is a call server.

Regarding hardware, you can either use voip (sip/h323/skinny) phones, or use a media gateway, like a cisco router, that will transform voip in pots/isdn and back.

Nice. That handles SIP. What about ISDN and SS7? No, wont handle - not VOIP. OP explicitely talks about telco protocols. –  TomTom Jun 17 '11 at 5:38
    
No. He does explicitely talks about SIP in the subject. And a Cisco or Alu mgw will handle nicely isdn trunks and phones. libss7 adds SS7 signaling capabilities to Asterisk, which would be great as wireshark would be able to decode it. –  petrus Jun 17 '11 at 9:51
