We want to purchase an AVAYA small office system to test/practice SIP trunking back to our 8700 before we roll out full scale to our branches in '12.

Maybe a hybrid, 4 analog lines and SIP lines?

Thoughts anyone?

IP Office IP500 with appropriate licenses and cards.

Agreed IP500. With R6, you can have a combo card, and have digital analog and 10 channels for IP phones. And also 4 analog trunk ports.

thanx all, already looking around
