Analyze signaling interworking latency (Post-Dial Delay) for SS7 to SIP gateways.
Awaiting Latency Inputs
When bridging legacy SS7 networks with IP-based SIP networks, the Interworking Function (IWF) introduces significant delays. This tool helps map out the contributors to Post-Dial Delay (PDD), ensuring compliance with carrier-grade voice quality standards.
Post-Dial Delay. The time between the last digit dialed and the receipt of a call progress signal.
Interworking Function. The component responsible for protocol translation (e.g., SIP INVITE to ISUP IAM).
Standard for interworking between Session Initiation Protocol (SIP) and Bearer Independent Call Control protocol or ISDN User Part.
