Hello.

I am thinking of upgrading my pbx ta824
I am thinking of voip technology like tde-100.
It should be compatible with tva50 voice mail that i have.

I need several ports that will accommodate my regular phones and fax etc

The problem is that i need to know what components need to be bought separately and what components are included with tde100.

I need the abilityto connect remote locations
I have several incoming voip providers

The phones that come with ta 824... Will they work with tde100 and if they do, will the features of tde100 be accessible?

I see that i can purchase tde100 from various sites but what is included vs what is not - thats the question.

So, i need help.

Thank you all in advance.
