Enterprise SIP Trunk Vs. IDA-PBreak the Limitation on T1

• Scales up by trunk only,

increments at 24

channels per step

• Limited to 24 channels per

trunk and the need to

install T1 cards circuits

IDA-P

• TDM-based, mainly for

voice communication

• Requires additional

IDA interface card

Enterprise SIP Trunk

• IP-based, supports not just voice but also video communication

• Highly dynamic channels, subscribe to what client’s need

• No channel limitations in the trunk, much faster to expand

• Lower CAPEX, no additional interface card required for channel expansion

What does really help to IT?
