Here is some information I found on the VU2ARC web site at
http://www.angelfire.com/in/BARC/inthemedia.htm
Long Range Cordless: HAMS Blamed

                  As you are all aware that the Long Range Cordless phones have
                  infested the 130-180 Mhz band, more so causing severe QRM to the
                  144 - 146 Mhz Ham band. These LRCs have a range of more than
                  15-20 kms. We in Bangalore face the QRM round the clock from
                  hundreds of these units and had reported the matter to WPC and
                  Dept Of Telephones, along with newspaper articles mentioning its
                  nuisance and illegality to create awareness among the general
                  public. Though some have refrained from using it, day by day more
                  and more are purchasing and operating them causing QRM not only
                  to hams but to the other authorised VHF band users like the Police,
                  Airband, Fire, Hams, etc, etc. In our newspaper articles we had
                  mentioned the extent of QRM it would cause to the various licenced
                  users but we received no response from WPC or DOT.

                  It has also been reported from various other cities and towns across
                  our country about the extent of QRM they cause. Now WPC has
                  woken up to the long range cordless QRM because it was observed
                  and reported by the Airline pilots around Rajkot and Ahmedabad
                  areas that the phone conversations were interefering with their
                  communication channels. It was first assumed to be Ham talk but
                  they have now understood it be from these LRCs. (lets not take the
                  blame for it, sitting quiet ) Wake up and pass on any kind of info to
                  WPC.

                  DGCA has made strong report of such QRM to WPC and as WPC
                  does not have wide and extensive monitoring setup has now
                  requested Hams to provide any kind of information with regard to
                  User names, phone nos, frequencies, etc OR even locations of such
                  long range cordless antennas. One could easily spot such antennas
                  because they look like a Trishul with ground radials. You may fax or
                  email the information to any one of the following:
