Voice Over IP

PathBuilder S200 series switch products support Voice over IP (VoIP) to provide 
termination and encapsulation of voice and fax traffic for transport over an IP 
network (see to Figure 1). 3Com’s proprietary protocol, Serial Protocol over TCP 
(SoTCP), provides the encapsulation mechanism for carrying voice traffic over an IP 
network.

VoIP provides new and cost effective solutions for a company’s telephony 
communication including:

• Long distance calling over an Intranet or the Internet

• Remote location dial-in and telecommuting

Key features include:

• real-time voice and fax over IP networks

• multiple SVCs over a single UDP session

• call management and signalling using TCP

These PathBuilder S200 series switches support VoIP:

• PathBuilder S21x switch

• PathBuilder S24x, 26x, and 27x switch
