PTA for IP Whitelisting to Curb Grey Telephony

ISLAMABAD, Pakistan: Pakistan Telecommunication Authority (PTA) is continuously taking measures to curb grey telephony which includes raids on illegal telecom set ups and whitelisting of Internet Protocols (IP) used to relay legitimate voice traffic.

In a press release issued on Wednesday, the authority said that to safeguard the legitimate voice communication, PTA has issued IP Whitelisting Regulations (Formerly IP whitelisting SoP). IP addresses being used by PTA Long Distance and International (LDI) licensees and PSEB registered call centers are registered (whitelisted) to ensure their uninterrupted voice operations.

In this regard, besides PTA LDI licensees, over 600 PSEB registered call centers have so far got their IP addresses whitelisted.

PTA has already intimated its licensees to ensure that only whitelisted IPs are used for commercial voice services by them and their customers.

The IP addresses which are not registered face periodic degradation for commercial voice services. Besides interruption of services, PTA also reserves the right to initiate further necessary action against the offenders as per the legal provisions.
