40 • Call router configuration

 

 

You may specify a whole subnet with the key parameter of the routing table entry. The format of the key parameter is ipaddress[/mask-size]; the mask size may be omitted.

Note Incoming SIP and H.323 calls use the calling party IP address property to store the IP address of the remote SIP user agent or H.323 terminal, respec- tively. Other interfaces like ISDN or FXS set the IP address to 0.0.0.0.

Example: Calling IP address routing table

The following example routes all calls from a remote H.323 terminal in the LAN to the next table TAB- FROM-LANand all other calls to TAB-FROM-WAN.

node(cfg)#context cs node(ctx-cs)[switch]#routing-table calling-ip ip node(rt-tab)[ip]#route 172.16.32.0/24 dest-table TAB-FROM-LAN node(rt-tab)[ip]#route default dest-table TAB-FROM-WAN

URI routing table

The calling party URI (calling-uri) table is used to route calls based on the URI of the originating VoIP peer, e.g. the From-URI of the incoming SIP call. The called party URI (called-uri) table is used to route calls based on the To-URI. The called URI of incoming calls is not set unless modified by a previous mapping table in the routing path.

You can use regular expressions to specify the parts of an URI that must match in order to route the call to a specified destination.

The following example shows how to create a routing table to route all SIP calls from John Smith to the next table TAB-FROM-JOHNwhile all other calls are routed to the next table TAB-FROM-UNKNOWN.

Mode: Context CS

Step

Command

Purpose

 

 

 

1

node(ctx-cs)[switch]#routing-

Creates a routing-table that examines the From-URI of an

 

table calling-uri name

incoming SIP call

 

 

 

2

node(rt-tab)[name]#route

Routes all SIP calls from john.smith@<anywhere> to the

 

sip:john\.smith@.% dest-table

table TAB-FROM-JOHN. Note that the dot (.) between john

 

TAB-FROM-JOHN

and smith must be escaped with a backslash (\), because

 

 

the dot (.) means ‘any character’ in a regular expression.

3

node(rt-tab)[name]#route default

Routes all other SIP calls to the table TAB-FROM-

 

dest-table TAB-FROM-UNKNOWN

UNKNOWN

 

 

 

Presentation Indicator Routing Table

The presentation indicator (calling-pi) table is used to route calls based on the presentation indicator of the calling party number. A user that doesn’t want its number being displays sets the presentation indicator to restricted. There is no presentation indicator on the called party number. Thus you cannot create a called- pi table.
