Configuration
Firmware version
All innovaphone devices use V9 hotfix 19 as firmware.
SIP - Trunk
- Gateway without Registration, Media-Relay must be selected.
- Internal GW to PBX
Number Mapping
Route Settings
- Force Enblock it's required for outoging calls.
Known Issues
- SIP Trunking with TDC it's based on a non-NAT solution. Provider does a direct link (via MPLS or VPN) to the costumer setup. During our tests was necessary to set media-relay and exclusive codec to pass in all call scenarios and have no issues with RTP handling since Provider didn't have IP route to phone's private network.
