Call-routing table parameters

LANconfig: VoiP Call Manager / Call router

WEBconfig: LCOS menu tree / Setup / Voice Call Manager / Call router

An entry in the call routing table consists of:

• Conditions that have to be met so that the entry is "considered" appropriate. This includes:
  • Information about which subscriber is to be called; called number/name (Called Party ID), called domain (if appropriate).
  • Information about the calling subscriber; calling number/name, calling domain, source line through which the call enters LANCOM VoIP Router.
• Instructions regarding the procedure for the call:
  • How is the telephone number converted and changed for further processing?
  • Which line should used to place the call (destination line)?
  • Which backup lines should be used if the destination line is not available?

The entries are searched row by row; the first suitable entry is performed. This is why the special entries should be configured first of all, then the general entries.

If an entry is found in the call routing table with the destination line "RESTART", then the complete pass starts again with the new, converted called party ID. The entry for the source line (calling line) is deleted for the next pass.

Both the call routing table and the local subscriber table can contain and process alphanumeric names where this makes sense.

• Active entry/default route, activeThe routing entry can be activated, deactivated, or marked as a default entry. All calls that can be resolved using the first passes but not using the call routing table or local subscriber table are then automatically resolved using these default entries. You can use any destination name and destination domain; only the source filters that are set are considered
• Priority of the entry, Prio The Call Manager sorts all entries with the same priority automatically, so that the table can be processed through logically from top to bottom. With some entries, however, the sequence of the entries has to be specified (for the telephone number translation, for example). The entries with the highest priority are automatically sorted to the top.
• Called number/name, Called ID The called party name or destination telephone number (without domain information) that is called. The # character is used as a placeholder for any character strings. All characters in front of the # are removed, the remaining characters are used in the "Number/name" field instead of the # character to further establish the connection. Example: The call routing table contains entry '00049#' as the called number/name and '00#' as the number/name. For all calls with a preceding '0' for outside-line access and the complete dialing code for Germany, only the leading '0' for the outside-line access and the leading '0' for the local area dialing code are retained as the number/name; the country ID is removed. So '00049 2405 123456' becomes '0 02405 123456'. Independently of this, an alphanumeric number can also be specified.
• Number/name, Dest-ID This telephone number is used to continue with establishing the connection. If no connection can be established using this telephone number and the corresponding line, then the backup telephone numbers with their associated lines are used At least one of "Number/name", "1st backup no." or "2nd backup no." has to be filled in. They are evaluated in this sequence. A blank field is skipped.
• Line, Dest-Line The connection is established using the destination line. Normal destination lines can be:
  • ISDN
  • All defined SIP lines.
  The following special functions can be entered as a destination line:
  • REJECT highlights a blocked telephone number.
  • USER forwards the call to local SIP or ISDN subscribers.
  • RESTART starts a new pass through the call routing table with the previously formed "number/name". The former "source line" is deleted.
  Note: This field has to be completed, otherwise the entry is not used.
• 2. Number, Dest-ID-2 This telephone number is used to establish the connection further if nothing is entered in "number/name" or the corresponding "line" is not available. If no connection can be established using this telephone number and the corresponding line, then the third telephone number and the third line is used.
• 2. Line, Dest-Line-2 The connection is established using this line if the second number is used to establish the connection. The same lines can be dialed as for "line".
• 3. Number, Dest-ID-3 Similar to the second number.
• 3. Line, Dest-Line-3 Similar to the second line.
• Called domain, Cld Domain This entry filters the called domain, the "Called Party Domain". The call router entry is only considered to match if the Called Party Domain for the call matches the domain that is entered here. If nothing is specified, any destination domain is accepted. The following can be entered as called domains:
  • ISDN
  • The internal VoIP domain of LANCOM Wireless Router.
  • All domains entered for the SIP and SIP-PBX lines.
• Calling number/name, Calling ID This entry filters the calling number/name, the "calling party ID". It is specified as an internal number or as a national or international telephone number. The domain is not specified. No "0" or other character for a line ID is prefixed; the ID is used as if it comes from the line or from internal telephone calls. The call router entry is only evaluated as matching if the Calling Party ID for the call matches the number that is entered here. After "#", any characters can be accepted. If nothing is specified here, any Calling Party ID is accepted. The following special functions can be entered as a calling number:
  • LOCAL restricts to internal telephone numbers (without a leading "0").
  • EMPTY can be used for Calling Party IDs that are not specified.
• Calling domain, Cln Domain This entry filters the calling domain. The call router entry is only considered to match if the Calling Domain for the call matches the domain that is entered here. If nothing is specified, each calling domain is accepted. The following can be entered as calling domains:
  • ISDN
  • The internal VoIP domain of LANCOM Wireless Router.
  • All domains entered for the SIP and SIP-PBX lines.
  SIP telephones usually have several line keys, for which different domains can be configured. With this filter, telephone calls are handled depending on the selection that is made using different line keys.
• Source line, Src-Line This entry filters the source line. The call router entry is only considered to match if the source line for the call matches the line that is entered here. If nothing is specified, any calling line is accepted. The following can be entered as the source line:
  • USER.ISDN for calls from a local ISDN subscriber
  • USER.SIP for calls from a local SIP subscriber
  • USER# for calls from a local subscriber in general
  • All ISDN, SIP and SIP-PBX lines that are entered.
