In Israel you can own a kosher cell phone. This means that you have a constant monthly payment with a bank of minutes you can use to call other kosher phones and landline phones. Taking pictures, surfing, sending SMSs and so on are disabled on the phone. The calls to non-kosher cellphones are much more costly. Kosher cell phones are backed by Rabinical authorities.
(There are some more details about this (that could be found here); I'm just presenting the main idea.)
From the above I conclude that common practice in Israel is that any landline phone is equivalent to a kosher cellular phone. From this I cannot derive what happened when landlines were first introduced, but anyway I suppose they were not criticized.
