Increasing number of small offices/home offices (SoHo) migrate to VoIP communication based on commodity appliances that provide the connectivity solution. The appliance is in many cases a combination of: * Residential gateway (RGW) * Integrated access device (IAD) * Key-system/ small PBX * SIP firewall / GW In some cases it even can be as part of a set-top box. All the above is based on SIP server technology that is tailored to embedded devices. This technology involves significant business potential as well as technology challenges that will be elaborated on the webinar.
