Fabian, Searching is a good start, but here are the answers to your questions anyway:
> 1- Transcoding: is this when you go from g711 to g729 for > example? Or when you go from SIP to IAx? Transcoding is converting audio data between codecs, like G711 -> G729. I wouldn't call SIP to IAX transcoding since the actual payload can be the same, but the signaling protocol is different. > 2- What is the best GUI tool to configure * ? Without being rude: your favorite text editor. GUIs tend to limit you as to what you can do. > 3- Do I need to install a PCI (fxo or fxs) to have meetme, music onnhold etc? No. Music on hold works in a VOIP only environment; there's ztdummy for meetme without zaptel hardware. > 4- If I have a SIP device behind a firewall the supports SIP transformations > (sonicwall pro230) and the * is outside the firewall, do I have to open ports > 5060 anyway? What about the audio? Don't know much about sonicawall. If you want to connect to the * server form the outside, you probably need to forward port 5060. If * from the inside "initiates" the connection then NATing works transparently. Usually you do not need to open ports for the RTP data path. But as I said, it all depends on your firewall configuration. The best thing to do is to try it out and see. --Luki _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
