Special Notes:

Due to individual Local Country regulations, Voice Calls bearing a CLI (Caller Line Identification) and terminating to the same country of origin, or those bearing no CLI at all, are subject to rejections from the Local Operators in order to protect their subscribers from unwanted/malicious/spoofing calls, since Local CLI calls cannot be entering a country’s International exchanges.

Unfortunately, due to the vast amount of Network Operators and changing regulations of each country, such types of calls might be observed to stop working without prior notice. For that reason, it is recommended that you use an International, and/or different to the termination country, CLI for your calls.


If your Business requires a Local CLI please feel free to reach out to your Account Manager / Sales representative to discuss your use case further.
