Handling of DSS1 AOC (advice of charge) in innovaphone Gateways depends on call routing
Applies To
This information applies to
- All innovaphone gateways and PBX platforms
All builds since version 5.
More Information
Problem Details
DSS1 (Euro-ISDN, E-DSS1) advice of charge information elements (AOC-x) are transparently passed through innovaphone gateways when a call is routed through the gateway routing component (aka “Relay”). However, when a call is routed through the PBX, AOC information gets lost.
When for example an innovaphone gateways is tied in to the trunk line of a legacy PBX, AOC is passed from the carrier’s trunk line to the PBX. However, when the call is routed through the PBX, then AOC information will be stripped. Note that this limitation is in the PBX, not the IP / H.323 protocol. That is, if a call is passed from one gateway to the other via IP, AOC is retained.
Resolution
If AOC is critical, do not route calls through the innovaphone PBX.
