DESCRIPTION
Select the authority group you want these extensions to belong to.
Type the first extension number for this range of extensions. Extensions can be
from 1 to 20 digits long.
Type the value of the increment, which the X6004 uses to create this range of
extensions.
Type the number of extensions you want to create. The number of extensions you
can create is limited by the subscription service registered on the X6004 (see
Section 32.4 on page 352.
When you create multiple SIP extensions, you automatically create SIP accounts
on the X6004. The user names for these SIP accounts are the extension numbers.
The passwords for the SIP accounts are also the extension numbers. To make the
passwords more secure you can add a prefix or a postfix to these extensions.
For example type "1" in the Prefix field and the SIP account passwords for the SIP
extensions you create become "1 + extension number".
You can enter up to three letters, numbers or a combination of letters and numbers
in the Prefix and Postfix fields.
Control how the X6004 handles the tones that the IP phones using these
extensions make when they push their buttons. One use of the tones is to
distinguish between numbers when trying to dial a PSTN phone number. You
should use the same mode as your VoIP service provider. The choices are:
• rfc2833 - Follow the RFC 2833 standard and send the DTMF tones in RTP
packets.
• inband - Send the DTMF tones in the voice data stream. This works best
when you are using a codec that does not use compression (like G.711).
Codecs that use compression (like G.729) can distort the tones.
• info - Send the DTMF tones in SIP messages.
