I do not have much knowledge about voip. My company is planning to have a VOIP(IPT) solution for upto 8 users. I don't kow what should I go for or what I need or even if this is possible, but the features should be:
-Should be able to switch phones from one location to another but extension remains same.(Like if user is moving to another room he just need to take his phone.)
-Extensions should also have direct phone numbers.
-Soft phone if possible(to connect via internet from anywhere in the world.)
