Configuration
Firmware version
All innovaphone devices use V8 HF5 build 80500.12 as firmware.
SIP - Trunk
First of all the SIP Trunk must be configured. Since the provider authenticates a user account only by IP - address, you cannot use the normal SIP-Gateway object. You need to configure a GW without registration and route the calls to the PBX.
Number Mapping
The provider uses for all numbers(incoming and outgoing) an international number format.
Route Settings
Because the provider doesn't support overlap sending, you must enable the block-wise sending of the phone number. You can do this by enabling Force enblock in your routes.
The second setting you must check is Interworking(QSIG,SIP). This feature must be enabled to properly relay supplementary services, like Hold over the SIP Trunk. If this checkbox is unchecked only basic call information like connect and disconnect will be forwarded by the gateway.
Fax
The FAX was connected via a IP302 to the IP800. When configuring the IP302 you must keep in mind that you will use the analog interface for fax communication. Thats why the T.38 codec must be enabled.
Now the PBX and the phones are setup correctly. You should be able to make call in both directions and send and receive fax messages.
