VoIP ports
The SIP server port and starting RTP port can be specified for the SIP server for a TalkSwitch
VoIP network. See VoIP ports on page 188.
SIP Server Registration Timer
The SIP Server Registration Timer can be specified for the SIP server for a TalkSwitch VoIP

UPnP
By default, TalkSwitch uses Universal Plug'n Play (UPnP) to attempt to automatically open the
required ports for VoIP communication through supported firewalls. By disabling this feature,
the ports must be manually configured within your firewall in order for VoIP communication to
operate.
For information on configuring your router ports for TalkSwitch VoIP networks, VoIP service
providers and external IP extensions, see Router port forwarding on page 36.
View Blocked IP Addresses
If TalkSwitch detects IP traffic that appears malicious or may impair operation of your phone
system, it will block traffic from the source IP address. The View Blocked IP Addresses area
provides a hyperlink to a page that displays blocked IP addresses.

through the firewall. See Router port forwarding on page 36.
