Controlling call-progress tones on a local Gateway
The Near End Cut Through parameter enables the call-progress tones from the distant PSTN to
be heard by the caller connected to the local MultiVoice Gateway. This provides answer
supervision support for MultiVoice Gateways using non-PRI trunks, by processing the call
progress tones from the distant PSTN.
Setting this value to Yes will enable passing the PSTN-generated call progress tones across the
IP network, using RTP packets between Gateways. These audio signals from distant PSTN are
compressed by the distant Gateway for transmission across the IP network, then uncompressed
by the local Gateway and played for the caller. Setting this value to No will cause the Gateway
to generate local progress tones in response to Q.931 messages.
Changes to this value become effective with the next call. This value defaults to Yes. Network
capacity and voice quality are the determining factors as to when this parameter should be
modified.
Single-stage dialing
The Single Dial Enable parameter is used to enable/disable single stage dialing of MultiVoice
calls. Setting this value to Yes enables the MultiVoice Gateway to extract the Dialed Number
Identification Service (DNIS) string from a single dialed entry. Setting this value to No
disables DNIS string collection, requiring users to dial the MultiVoice Gateway, first, wait for
a dial tone form the MultiVoice Gateway, then dial the called telephone number. This value
defaults to No. Changes to this value become effective with the next VoIP call.
Single stage dialing will work with MultiVoice Gateways under the following conditions:
•
You are using T1 inband trunks, and the switch (or PBX) can relay DTMF signals to the
MultiVoice Gateway.
•
You are using T1 PRI trunks.
•
You have enable collection of DNIS on the MultiVoice Gateway. (For information on
configuring DNIS collection see “Collecting DNIS and ANI” on page 5-4.)
MultiVoice configuration examples
Configuring Gatekeepers
To configure MultiVoice communications with a primary Gatekeeper:
1
Open the Ethernet > Mod Config > VOIP Options menu.
2
Press Enter to open the edit field for GK IP Adrs:
GK IP Adrs:
[0.0.0.0]
3
Enter the IP address of the MultiVoice Access Manager. For example:
GK IP Adrs = 10.10.10.10
The MultiVoice Gateway must be able to send packets to and receive packets from the
MultiVoice Access Manager. You can verify connectivity by Pinging the IP address of the
MultiVoice Access Manager from the MultiVoice Gateway terminal server. If the Pings
fail, see your network administrator about possible routing problems.
