the IP telephony protocol used on the telephony switch interface. The telephony switch vendor should be able to supply the port numbers used by the protocol.

The NetLink Wireless Telephones, NetLink Telephony Gateways, and NetLink SVP Server use TCP and UDP and other common IP protocols from time to time. These include DHCP, DNS, WINS, TFTP, FTP, Telnet, ARP, and ICMP. SpectraLink uses proprietary UDP channels between the infrastructure components that use UDP ports 5454 - 5458. The push-to-talk (PTT) mode of the NetLink i640 Wireless Telephone uses the multicast IP address 224.0.1.116, which is also used by the NetLink Wireless Telephones and infrastructure components to locate and maintain each other.
