The Landline subscribers of an operator miss their calls when

.  they are not near the phone and not available

.  phone is out of order, or 

.  when they are busy on another call

This reduces  the  call  completion  rate and hence, is  a  source of revenue  loss for  the  operator.  Missed  Call  Alerts  service  is  a  solution  for  notifying  users about  their  missed  calls,  thereby  encouraging  them  to  make  return  calls  as per their choice

5.  Local Number Portability

Local Number P ortability  was defined  in  the Telecommunications Act  of  1996 as the "ability of users of telecommunications services to retain,  at the same location, existing telecommunications numbers without impairment of  quality,reliability,  or  convenience  when  switching  from  one  telecommunications carrier  to  another."  LNP  is  a  consumer's  ability  to  change  service  providers within  the  same  local area  and still  keep the same  phone  number.  It  allows consumers  to  switch  from  one  carrier  to  another  within  the  same  general metropolitan area.

5.  Virtual Calling Card

7.  Push-To-Talk over Cellular

Push-To-Talk over Cellular (PoC)  provides users with a walkie o talkie kind of experience  in their network. This  product  requires  mandatory  end to  end  IP infrastructure and so can be offered in GPRS, EDGE, PDSN, 3G networks only. This  product  packetises  voice  and  thus  saves  valuable  channel  resource  for the  operator.  Media  resources  are  reserved  only  for  the  duration  while  the user is speaking or listening. ps one of the greatest benefits that wireless  carriers enjoy from  PoC is the network cost efficiencies that are realized in at least two ways.  Use of the underlying  IP-based  network  with  half-duplex  transmissions  has  the advantage of both requiring less bandwidth (e.g. network and facility savings) as  well  as  avoiding  interconnection  to  the  PSTN  (e.g.  savings  against interconnection charges).
