Phone Number Format

The service supports 2 types of phone number formatting: TAPI (regular public telephone system format) and SIP (Internet-based phone number format).

TAPI Format

All numbers must be formatted according to the universal TAPI (E164) convention as follows:

1. Country/Region
2. City/Area Code
3. Local Number
4. Extension

The following are all TAPI-compliant formats::

• +1 (514) 555 1212
• +1 (514) 555 1212 x201
• +33 (1) 4331 1212
• +44 (3456) 6789

SIP Format

SIP phone numbers are entered in the standard SIP format as follows:

• sip: as the SIP Prefix
• Phone Number or User ID: telephone number or name of the SIP phone subscriber.
• The @ sign.
• Provider Host Name or IP Address: the host name or IP address of the subscriber's SIP Telephony Provider (SIP gateway or Softswitch).

If the IP telephony provider requires authentication, enter your account credentials to be authenticated in the fields below:

• User Name: Your account user name
• Password: Your account password

As an example, sip:john.smith@mycompany.com or sip:15145551212@mycompany.com or sip:john.smith@192.168.12.233 are valid SIP phone numbers for John Smith.
