How To Block Anonymous & Origin Based Caller IDs in TCXC

Recently the traffic originated from certain countries terminating in the some destination networks will be priced $10 in some cases. To avoid this issue we sellers may use the below feature to block such traffic originating from certain CLIDs.

Example of  caller id surcharge applied:

Please be aware that networks in SAUDI ARABIA, UNITED ARAB EMIRATES and TURKEY MOBILE TURKCELL are charging   for calls sent with a blank or manipulated CLI.  

Soon carriers will also take the necessary precautions to ensure that any traffic with “no CLI” or “short CLI” are priced 10 $, however if a call is sent with what appears to be a valid A number, but is later shown by the terminating network to be a manipulated or modified A number (e.g. over-stamped), they reserve the right to recalculate the billing for those calls. You may buy a phone number and use it when sending out calls if you’re unsure if your caller ids are:

TCXC Smart Contract: Blockchain Implementation For Telecom Providers


Telecommunications companies have been going back and forth on how blockchain can benefit their operations. I have seen lots of content out there but no real world example on how it’s implemented by a communications service provider, therefore i want to share with you how TelecomsXChange decided to use blockchain to improve a specific part of its platform, where we thought decentralizations makes sense. While also making sure that we make it affordable for communication service providers (CSPs) to utilize it.

In my opinion utilizing the blockchain in telecom shouldn’t be complicated, At TelecomsXChange, we always aim to make advanced technologies simple, we took the time it takes for CSPs to interconnect from months or years to seconds.

The Mission

Here is what we want to achieve, give buyers or sellers a one click option and or a single API call to keep a replica of important data on the blockchain, like prepaid account balances on daily basis, and an easy way to verify the transactions and view its content in a human readable format (Text) not just hexes or binaries.

As shown below, to achieve this will develop a Smart Contract on ETC network, it will be responsible for storing the data we push from TelecomsXChange on to the blockchain.

E.212 to E.164 Mapping (Voice – SMS Unification)

SMS Termination Rates (E.212 -> E.164)

There are three types of GT in use in mobile networks known as E.164 (MSISDN), E.212(IMSI) and E.214(MGT):

Billing systems understand to charge according to E.164 format (CC+AC) but all SMS termination providers send you their updated lists in E.212 format (MCCMNC).

So to solve this problem you would assume that there is a list ready that you can use to map the E.164 and E.212 together. I thought so too but unfortunately there isn’t an accurate single list available on the net that would provide you that.
