WHITE PAPER SERIES - Reliance Communications

PROBABLE CHALLENGES
The service provider needs to have an Intelligent Network platform capable of supporting the
features mentioned above. An error-free reverse billing capability should be available in the
billing system. Above all, the service provider has to have the necessary agreements with other
service providers for accessibility.
Since toll free is a virtual number, basic telephony service needs to be in place at the user’s
end. Because of the regulatory requirements, it is mandatory to have both, basic as well as toll
free service from the same service provider. Generally, the toll free number is mapped to a E1
PRI number to support multiple simultaneous calls; however, depending on the expected call
volume, the mapping can also be done on a set of fixed (wire line / wireless) or mobile phones.
Multiple phones are part of a single hunt group to support simultaneous calls. The call flow of a
Mumbai caller using non-Reliance phone to reach a Toll Free number of Reliance terminated in
Delhi is shown below:
Accessibility from all service providers can sometimes be a challenge as new service codes
(SCP codes) are getting added and new operators are also getting introduced in India. The
service provider must have the necessary resources to carry out the accessibility testing (codewise
and operator-wise) at regular intervals.
For the user, correct sizing of the set up is crucial. For effective campaigns, there could be a
sudden surge of calls on the toll free. It is the last thing to expect that the toll free number is
engaged. The user can also take the help of the load balancing feature available from the
service provider to manage this problem. Geographical and time based distribution of calls can
further help to overcome this challenge.
