The country’s telecom regulator has recently issued a letter to state-run mobile phone operator Teletalk asking it to effectively use the illegal call termination detection system.
The Bangladesh Telecommunication Regulatory Commission letter also asked Teletalk to maintain the standards of using a SIM detection box, an automated system for tracking illegal call termination, as the regulator earlier detected inconsistencies.
BTRC officials said in a recent finding the regulator came to know that Teletalk was using the detection system in a span of as long as 29 days.
‘The time-span of using the SIM detection box by Teletalk was ranging from 10 days to 29 days,’ a senior BTRC official told New Age last week.
He also said according to the BTRC directive the operators were supposed to run the SIM detection system three times a day.
He, however, said the BTRC earlier wrote several times to Teletalk in the same issue but taking the advantage of being a state-owned company the issue remained ignored.
The BTRC officials also said some Teletalk officials were involved in illegal call termination and hampering the regular operation of automated detection system.
The illegal use of voice over internet protocol by Teletalk was recently exposed after three mobile phone companies — Grameenphone, Banglalink and Robi — in a joint letter to the BTRC had said that Teletalk’s SIMs were being used for the use of illegal VoIP, causing revenue losses to the stakeholders.
The three operators in separate analyses to the BTRC for April-June period showed that the trend of Teletalk SIM use for illegal VoIP was higher.
The letter also said the SIM Box Detection System, a system for tracking illegal VoIP, detected huge number of Teletalk SIMs compared with others.
The data showed that in May 28-June 27, the SIM Box Detection System found 38,613 VoIP SIMs of Teletalk while the numbers were 6,080 for Airtel, 1,217 for Robi, 511 for Banglalink and 472 for GP.
