For domestic and toll-free outbound calls, the caller ID presented to the called party is in local format and delivery is not guaranteed. For international outbound calls, caller ID is presented in +E.164 format.

DTMF support

DTMF (Dual-Tone Multi-Frequency) signaling uses RFC 2833 format and is supported for both inbound and outbound calls.

Emergency services

Calls to emergency services numbers in Romania are not supported. Do not rely on voice calling for emergency service access.

Special requirements

Outbound calls in Romania are restricted to carrier-owned numbers due to ANCOM regulatory requirements targeting caller ID spoofing and fraud prevention. Ensure that any Romania numbers used by the “Outbound Numbers” setting or toll-free calls are carrier-provisioned numbers assigned to your account.

Compliance note

These guidelines summarize carrier requirements at the time of publication and do not constitute legal counsel. Verify that your implementation complies with all applicable telecommunications regulations in Romania.
