Currently I do my internship in a small entreprise and I need to develop a softphone for mobile with j2me that will operate with the company pabx as voip server.
the pabx has a private address behind a router, I have created sip accounts on the pabx, I want to know if it is possible to make the pabx visible on the internet (If yes how)? to make calls from my sip softphone using the internet.
Thank you.
pabx type: Avaya IP Office 400
