IMPORTANT! Flowroute uses the E.164 format, which requires 11 digits for domestic numbers and can be up to a 15 digits for international numbers.
Domestic calls
The domestic E.164 number is typically formatted as a North American Numbering Plan Administration style: +1(NPA-NXX-XXXX). The prefix (+) is not required for outbound calls and should not be included in dialing.
For Example,
Test call from USA to USA:
1-123-123-4433
International calls
When dialing internationally, include the International Access Code followed by the E.164 country code and international local number format: [(IDD prefix)[country code](International DID)]
For example,
Test call from the USA to Philippines:
63-2-2479-7000Test call from Philippines to USA:
1-232-234-2676
Reasons for failed calls
If an outbound number is dialed through Flowroute without adhering to these guidelines, the connection may fail in several ways:
The malformed outbound number incorrectly dials a different country or location if the length of the dialed number is incorrect
The malformed outbound number will fail completely due to the dialed number not having any destination in that format
The malformed outbound number will fail because fraud protection enforces the destination cost limitation. This means that calls exceeding your set cost limit will not be allowed to establish. You can review and adjust your fraud prevention settings in the Manage portal.
