Introduction

About SIP URI options

HINT:

Defining options and numbers for reaching a user on the ISDN/NET network is more

convenient if you first define the user in the endpoint address book.

Dialling from the endpoint

Dialling from the endpoint is done using the SIP protocol. In order to inform the ISDN Link about

destination number to call etc, the following optional SIP parameters must be used. Each option

key or value is preceded with a semicolon, ";" .

x-h320number=NUMBER

Replace NUMBER with the destination number to call, normally consisting of digits. Please notice

that when dialling an ISDN network destination which requires sub-addressing, the sub-address

number is provided in the following format:

x-h320number=NUMBER*SUBADDRESS

When using the NET (External) interface, providing a number may not be required, and this option

can be skipped in those cases.

Furthermore, when using the NET interface, the NUMBER may consist of digits, * and #. In the rare

situation that a # is required in the number, it must be encoded as %23. So to dial 123#* on the

NET interface, NUMBER must be set to 123%23*.

x-h320restrict=true|false

Some networks (generally only applicable to North-America) only support restricted mode (ie

56kbps per channel instead of 64kbps per channel). By default, unrestricted mode is assumed.

Notice that the default restrict mode assumption can be changed with the following configuration:

xConfiguration H320 DefaultCall Restrict

Making audio calls

x-h320tlph=true|false

This option is used when making a simple audio only telephony call to an ordinary telephone

destination. Please notice that the x-h320restrict option has no meaning with this option, and must

not be used.
