TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 3 of 84 1 The T ANDBERG API This document is a guide to the API interface of the TANDBERG Gatekeeper and Border Controller products. All rights reserved. This document contains informatio n that is proprietary to TANDBERG.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 4 of 84 1.1 Introduction to XML XML is a markup language for documents containing structured information. All information elements in an XML document are marked by a tag and a corresponding end-tag.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 5 of 84 Example 1.3 If we now look at the NTP element once NTP has been correctly configured we see that it now contains more sub-structure: <Status> <NTP item="1" status="Active"> <Address item="1">10.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 6 of 84 1.2 Introduction to XML Path Language (XP ath) XPath is a comprehensive la nguage to address data in XML documents. It is, howe ver, very simple to understand the basics.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 7 of 84 Example 1.7 When using XPath it is possible to omit specifying inte rmediate levels in the address expression. By using the powerful “double slash" you can address elements without having to specify the complete path.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 8 of 84 1.3 The TANDBERG XML Engine The TANDBERG XML engine is optimized for advanced machine-machine interaction between a TAND B ERG s ystem and an ex t ern al co nt rol a p plic at ion.

TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 10 of 84 Example 1.9 The el eme nt Zone will contain dif f erent sub elements depending on the zone status: <Status> <.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 11 of 84 Example 1.10 From the XML structure below we see that the Speed element of Ethernet[1] is configured to Auto . The Speed element references the EthernetSpeed ele ment i n th e ValueSpace document, showing the value domain for this configuration.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 12 of 84 Example 1.11 The command Dial is defined to take five parameters. Only the callSrc and callDst parameters are required; this is specified by the attribute required . The value domain for the parameters is referenced by the attribute valueSpaceRef .
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 13 of 84 Example 1.13 The Dial command in the above example may return the following response structure: <Command> <DialResult item="1" status="OK"> <callSrc item="1">alice@example.
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 14 of 84 1.5 Introduction to TANDBERG XML API Service (TXAS) TXAS is a service provided by TANDBERG un its for transmitting and receiving information encoded in XML format. The API uses HTTP(S) as the transport mechanism and connects to the normal web port (80).
TANDBER G Gatekee per/Bord er Contro l ler API Us er Guide D14172.01 page 15 of 84 Like getxml, it has the data URL form-data encoded with one single parameter. The Content-Type of the document must be of type “application/x-www-form-urlencoded" and the body mus t be encoded accordingly (e.
