TALKSWITCH VOIP NETWORK TROUBLESHOOTING GUIDE 1. INTRODUCTION This guide assumes you are having difficulties with VoIP calls in a branch-to-branch configuration and you have already configured the following configuration settings in both the proxy server and remote site locations: • • • IP addresses for private, public and proxy server network settings. VoIP and Line Hunt Group numbers. Services in the router IP mapping tables.
TALKSWITCH VOIP NETWORK TROUBLESHOOTING GUIDE 2. VERIFYING CONFIGURATION SETTINGS Verify the TalkSwitch unit configuration settings contained in this section for the remote site and proxy server locations. This section also lists additional configuration setting information to help you determine possible errors in your TalkSwitch settings. 2.1 IP CONFIGURATION The System IP Settings section displays the TalkSwitch unit private IP address.
TALKSWITCH VOIP NETWORK TROUBLESHOOTING GUIDE Verify that the MAC address is reserved or that the firewall supports UPnP (firewall specific information). If the Unit IP Address is public, ensure the unit is not behind a firewall. Test: Ping the IP address to verify that it is valid. 2.1.2 Public WAN IP Address If the IP address is static, verify the address. If the IP address is dynamic, check the address using an address-server checker (such as checkip.talkswitch.com).
TALKSWITCH VOIP NETWORK TROUBLESHOOTING GUIDE rechecking this box updates the Server Names entries. The Registrar Authentication option turns authentication on or off. If this location is the proxy/registrar, make sure the box is checked and verify the server name addresses and that both the proxy and the registrar entries are the same. If FDQN is used, make sure the entries are typed correctly. Verify that all locations have the proper proxy/registrar IP addresses.
TALKSWITCH VOIP NETWORK TROUBLESHOOTING GUIDE 2.4 LINE HUNT GROUPS The Set Line Hunt Group options are found in System Information -> Line Hunt Groups. Choose a hunt group and TalkSwitch VoIP Numbers as the Line Type.
