Cannot Make A Connection; Ip Trunk Does Not Appear In Trunk View - Altigen AltiWare OE Release 4.0 Getting Started Manual

Cannot Make a Connection

1. Check Network Connectivity Using "ping"
2. Check Network Firewall Settings - See "Network Configuration
Guidelines for VoIP" on page 48 for more details.
3. Check IP Address of Destination System
4. Check the RTP and RTCP Settings - Make sure UDP port numbers
49152-49199 are not assigned to other applications. RTP/RTCP is the
acronym for Real-time Transport (Control) Protocol, a transport
protocol for real-time applications used to transport packetized voice
packets over the IP network.
5. Check the AltiWare IP Dialing Table for Dialed Digits Length -
Refer to "IP Dialing Table" in Chapter 2 of the System Administration
Manual.
6. Check if Called Extension is a Workgroup or has Multiple Call
Waiting Enabled - when the called party is a workgroup pilot number
or has Multiple Call Waiting enabled, the caller is placed on hold and
hears ringback or music.

IP Trunk Does Not Appear in Trunk View

When an IP trunk doesn't appear in the Trunk View, there are two possible
causes:
1. Device Driver is Not Running - check the device driver. Make sure
it's installed and working properly.
Windows NT 4.0 does not support Plug and Play. Therefore, the PnP
ISA Enable Driver (PNPISA.SYS) must be installed if it is not
installed already. Refer to the Microsoft Web site for installation
instructions.
2. Triton VoIP Board is Not Installed Properly - Refer to the Triton
Board Quick Installation Guide for more details on proper installation
of the Triton VoIP board.
