Configuration
Firmware version
All innovaphone devices use V9 Hotfix20 as firmware.
SIP - Trunk
Number Mapping
Route Settings
Redundancy
The solution for redundancy, it is not straight forward.
As a workaround in cases with forwarding to SIP URI Port can using the domain name instead of IP. In this case Provider can configure DNS server to send the requests to slave PBX if the master PBX is not available.
Known Issues
- Reverse Media Negotiation - This feature it's not supported, due that fact it's necessary to set Exclusive Codec and Media-Relay options in the SIP Trunk configuration.
- No T.38 - During the SIP negotation T.38 was accepted however the fax transmission fails.
- Interworking/QSIG could cause issues, reported by costumer when performing Hold and using Interworking/QSIG flag on the routes the media change offer sent to the Provider was rejected. So the solution should be not use this option as shown in the configuration above.
