Common mistake in VOIP International Call Service

To gain more Average Revenue per User (ARPU) by increasing calling traffic from their customers, fixed wireless CDMA telecommunication operators used to have specific prefix number to make a long distance call. As we know that the mobility of their customers are limited by area/region and some of them have no directly Long Distance Call Service (SLJJ) license. So, to provide long distance call for their customers usually they provide specific dial access code. But this method is working only for their customers; it means the same dial access code will not work once we try to call to another telecommunication operator’s number. Through specific dial access code, telecommunication operators will give cheap tariff to the customers.
Usually telecommunication operators used to have VOIP International Call Service to provide international call for their customers. It is the same thing with long distance call service through own network (own-net), telecommunication operators used to specify dial access code during make a call but it is different access code with long distance call. And it is the same reason that through VOIP International Call Service, customers will pay cheap for their calling session. Through both methods, telecommunication operators hope their ARPU will increase every month
Unfortunately sometimes it is not running as we expected once both access codes for VOIP International Call Service and Long Distance Call Service are a little bit confusing. This will show you a case how this is happening
For example a fixed wireless CDMA Telecommunication operator has both service and below is the access codes for both;
To make a call for;
1. Long Distance Call Service = 01010 + Area Code with (0) + Destination number
Example;
a. Jakarta customer need to call to Bandung, then he/she must dial 0101002291312xxx
b. Surabaya customer need to call to Balikpapan, then he/she must dial 0101005429234xxx
2. VOIP International Call Service = 01010 + Country Code + Area Code + Destination number
Example;
a. Jakarta Customer need to call to Singapore , then he/she must dial 01010 6564xxxx
b. Surabaya customer need to call to India, then he/she must dial 01010919703012xxx
As you saw above access codes for both VOIP International Call Service and Long Distance Call Service is the same (01010). This is a little bit confusing for customers if they are in the first time to make a call for both services. For them who used to make a call for both service definitely will be no issue
This is common mistake once customers need to make a long distance call service but they are using invalid access code
For example;
1. Jakarta customer makes a call to Jambi customer. Unfortunately they dial with 01010 7419701xxx
Since the prefix is invalid, then the calling will be forwarded to Russia
The valid call is 010100 7419701xxx
2. Bandung customer makes a call to Makasar number by dialing 01010 4119144xxx
Since the prefix is invalid, then the calling will be forwarded to Switzerland
The valid call is 010100 4119144xxx
3. Medan customer makes a call to Yogyakarta customer by dialing 010102749221xxx
Since the prefix is invalid, then the calling will be forwarded to South Africa
The valid call is 0101002749221xxx
4. Medan customer makes a call to Purwakarta customer by dialing 01010264916xxx
Since the prefix is invalid, then the calling will be forwarded to Namibia
The valid call is 010100264916xxx
5. Semarang customer makes a call to Malang customer by dialing 010103419776xxx
Since the prefix is invalid, then the calling will be forwarded Spain
The valid call is 0101003419776xxx
6. Bandung customer makes a call to Denpasar customer by dialing 010103619645xxx
Since the prefix is invalid, then the calling will be forwarded Hungary
The valid call is 0101003619645xxx
For all common mistake above, the call will be disconnected since usually the destination number is incomplete for each country. And for all that common mistake, customer will be not charged
