I don't understand why it's stated that the 7170 can be connected up to 3 analogue phones if the analogue port is only 1. The 7050 has 3 port for 3 analogue phones, but how is it possible to manage up to 3 analogue phones(not more) with only 1 analogue port?! Is there an adapter?
If the connection goes in parallel then it can be connected more than 3 phones, but there is stated max 3, so i guess it's not a matter of parallel connection...
