SLIDE 72
SIP Pro’s
SIP has been around longer and has much greater adoption in the industry Greater numbers of hardware manufacturers (PBX, IP Phones) implement SIP than IAX in their equipment There is a much more broad audience looking at and using SIP . Because of this you will find many more SIP tools (diagnostic, monitoring, load testing, etc) than IAX tools.
