Universal Network Terminal TAU-32M.IP 87
2.
To route outgoing calls via SIP-T protocol, you should configure prefixes with the corresponding protocol
(Protocol & Target: SIP-T Direct IP) and the type of the number fetched by the prefix (Number type). For
description of parameters, see Section 5.1.2.2.5.1;
3.
To assign Caller ID category to the subscriber, use SS7 category (SIP-T) parameter in subscriber port
configuration or subscriber profile. For description of parameters, see Section 5.1.2.4The Ports
Configuration of Subscriber Ports submenu (Ports).
4.
To receive international calls with '+' symbol preceding the number, you should configure 'User=Phone'
option, see Section 5.1.2.2.3).
5.1.2.2.2
The 'H.323 Protocol' submenu
In
'H.323'
submenu, you can configure H.323 protocol settings.
H.323 standard states specifications for audio and video data transmission via data networks and includes
standards for video and voice codecs, public domain applications, call and system management.
The H.323 stack of the TAU-32M.IP gateway supports the following protocols:
–
H.245
is used for codec matching and opening of voice connection when faststart procedure is not used;
–
Q.931/H.225
–allows to establish and control a connection;
–
RAS
–allows for gatekeeper interactions;
–
H.235
–authenticates calls during gatekeeper interactions;
–
Н.450.1
–used during put on/remove from hold.
Gatekeeper
allows for call processing inside its zone and interaction with other zones as well as call
management. During gatekeeper operations, the gateway should register on the gatekeeper and perform
authorization using login and password (Н.235) depending on the local network policy. Only after successful
registration gateway subscribers will be able to perform calls through the gatekeeper. Gateway registers on the
gatekeeper for a limited amount of time –
Time to live
(TTL) – during which it should renew its registration.
Keep
alive
timer is used for this purpose; upon expiration, the gateway sends a renewal request.
Faststart procedure enables 'fast' establishment of a voice connection. In this case, channel will be established
before the start of capability coordination with H.245 protocol. Tunnelling procedure allows to transfer H.245
signalling via Q.931 signal channels. As a result, no additional TCP connection (or TCP port) is required for capability
coordination.
H.323 protocol operation is possible only when Profile 1 is used. Use Profile 1 to configure codecs
and routing when Н.323 protocol is used.
You don't have to reboot the gateway in order to apply H.323 settings. When applying settings,
all current calls will be terminated!
