SIP User's Manual 3. Web-Based Management

Parameter Description

SAS Registration Time

[SASRegistrationTime]

Determines the value of the SIP Expires header that is sent in a 200

OK response to an incoming REGISTER message when in SAS

'Emergency Mode'.

The valid range is 0 to 2,000,000. The default value is 20.

Short Number Length

[SASShortNumberLength]

This parameter is obsolete; instead, use the parameter

SASRegistrationManipulation.

SAS Local SIP TCP Port

[SASLocalSIPTCPPort]

Local TCP port used to send/receive SIP messages for the SAS

application. The SIP entities in the local network need to send the

registration requests to this port. When forwarding the requests to the

proxy ('Normal Mode'), this port serves as the source port.

The valid range is 1 to 65,534. The default value is 5080.

SAS Local SIP TLS Port

[SASLocalSIPTLSPort]

Local TLS port used to send/receive SIP messages for the SAS

application. The SIP entities in the local network need to send the

registration requests to this port. When forwarding the requests to the

proxy ('Normal Mode'), this port serves as the source port.

The valid range is 1 to 65,534. The default value is 5081.

SAS Proxy Set

[SASProxySet]

Determines the Proxy Set (index number) used in SAS Normal mode

to forward REGISTER and INVITE requests from the users that are

served by the SAS application.

The valid range is 0 to 5. The default value is 0 (i.e., default Proxy

Set).

Redundant SAS Proxy Set

[RedundantSASProxySet]

Determines the Proxy Set (index number) used in SAS Emergency

mode for fallback when the user is not found in the Registered Users

database. Each time a new SIP request arrives, the SAS application

checks whether the user is listed in the registration database. If the

user is located in the database, the request is sent to the user. If the

user is not found, the request is forwarded to the next redundant SAS

defined in the Redundant SAS Proxy Set. If that SAS Proxy IP appears

in the Via header of the request, it is not forwarded (so that loops are

prevented in the request's course). If no such redundant SAS exists,

the SAS sends the request to its default gateway (configured by the

parameter SASDefaultGatewayIP).

The valid range is -1 to 5. The default value is -1 (i.e., no redundant

Proxy Set).

3.4.4.3 Configuring the Number Manipulation Tables

The device provides four Number Manipulation tables for incoming (IP-to-Tel) and outgoing

(Tel-to-IP) calls. These tables are used to modify the destination and source telephone

numbers so that the calls can be routed correctly. For example, telephone number

manipulation can be implemented for the following:

 Strip or add dialing plan digits from or to the number. For example, a user may need to

first dial 9 before dialing the phone number to indicate an external line. This number

(9) can then be removed (by the Manipulation table) before the call is setup.

 Allow or disallow Caller ID information to be sent according to destination or source

prefixes. For detailed information on Caller ID, refer to Caller Display Information on

page 177.
