MP-1xx H.323 User’s Manual 8. Gateway Capabilities Description
Version 4.4 155 March 2005
• DNS resolution – When host name is used (instead of IP address) for the destination route, it
is resolved to an IP address by a DNS server. Connectivity and QoS are then applied to the
resolved IP address.
8.4.3 Relevant Parameters
The following parameters (described in Table 5-11) are used to configure the Alternative Routing
mechanism:
• AltRoutingTel2IPEnable
• AltRoutingTel2IPMode
• IPConnQoSMaxAllowedPL
• IPConnQoSMaxAllowedDelay
8.5 Working with H.450 Supplementary Services
The MP-1xx H.323 FXS and FXO gateways support the following supplementary services:
• Hold / Retrieve (H.450.4); refer to Section
8.5.1.
• Consultation / Alternate; refer to Section
8.5.2.
• Transfer (H.450.2); refer to Section
8.5.3.
• Call Forward (H.450.3); refer to Section
8.5.4.
• Call Waiting (H.450.6); refer to Section
8.5.5.
• Message Waiting Indication (MWI) (H.450.7); refer to Section
8.5.6 on page 157.
• Name identification (H.450.8); refer to Section
8.5.7 on page 157.
To activate these supplementary services (Hold, Transfer, Forward, Waiting, MWI and name
identification) on the MP-1xx gateway, enable each service’s corresponding parameter either
from the Web Interface or via the ini file. Note that all call participants (H.323 endpoints) must
comply with the H.450 1-4 standards.
Note: When working with application servers (such as BroadSoft’s BroadWorks) in
client server mode (the application server controls all supplementary
services and keypad features by itself), the gateway’s supplementary
services must be disabled.
8.5.1 Call Hold and Retrieve
• Active calls can be put on-hold by pressing the phone's hook-flash button.
• The party that initiates the hold is called the holding party; the other party is called the held
party.
• After a successful hold, the held party should hear Held Tone and the holding party should
hear Dial Tone.
• A retrieve can be performed only by the holding party while the call is held and active.
• The holding party performs the retrieve by pressing the hook-flash.
• After a successful retrieve the voice should be connected again.
8.5.2 Consultation / Alternate
• The consolation feature is relevant only for the holding party (applicable only to the MP-
1xx/FXS gateway).
