International Calling Restrictions
Mainland China
Due to strict traffic profile monitoring by local network operators meant to reduce telemarketing and unwanted calls to Mainland China, VoIP calls to Mainland China are not allowed.
Israel
Due to additional requirements enacted by the regulatory body in Iran, voice calls and SMS/MMS traffic to Iran is not allowed and will be blocked by the carrier.
Restrictions on Domestic calls in India
Calls will not route outbound to India if they are made from an Indian number (+91). This is due to increased regulations and enforcement by the Telecom Regulatory Authority of India (TRAI) which restrict mixing international VoIP and local PSTN traffic.
Restrictions on Domestic Calls in United Arab Emirates (UAE)
UAE geographic and toll-free numbers are restricted to domestic use. All voice calls must terminate within the country, and local carriers block international routing for these numbers. As a result, such numbers can only be assigned to users who are physically present in the UAE, in compliance with local telecom regulations.
