Telos Zephyr Xstream User Manual page 115

NOTE: Call from a Zephyr Xport that is calling from a POTS (analog) line is considered a Phone
mode call.
Interface
This allows you to choose between the ISDN, Ethernet and, if you have the optional V.35/X.21
interface, V.35. To use the V.35/X.21 interface choose V.35 Split or V.35 Single. To use the
built‐in ISDN interface set this to ISDN. To stream IP over the Ethernet choose Ethernet.

HOT TIP!
Choosing Ethernet or V.35 Single will change the available options for the CODEC and
DIAL menus. See Appendix 7 (Special Operational Modes) for additional information.
Prefix
This will generally be left blank. Any number(s) entered in this field will be appended to the
beginning of any number entered when dialing (either manually or by using Dial Setups). The
most common use of this is when your ISDN circuit requires that a "9", "8", or other digit be
used before dialing a number.
Since your Xstream may be moved from line to line, and not all lines may need this prefix, we
allow you to enter this prefix here, so you can omit it from Dial Setups. In this way the same Dial
Setups can be used on different lines.
TEL - Screen 4
Pressing the TEL a fourth time will show this menu. These are the settings for the ports used for
incoming and outgoing connections in the SIP and RTP Ethernet interface modes. The default
ports are shown above. Please refer to Appendix 6 for more details on port assignments.
The options for this menu are as follows:
SIP Port
This is a TCP port used by the Xstream to set up a bi‐directional Ethernet streaming connection.
