Howto:Telenor SIP Provider Compatibility Test
Innovaphone Compatibility Test Report
Summary
SIP Provider: Telenor(Norway)
The provider does not support all required innovaphone features and is therefore not qualified as recommended SIP Provider.
The main reason for not passing the tests, is the missing DDI feature on provider side. By not supporting DDI this provider cannot be used for larger(more than 15 extensions) installation. As a customer you can connect up to 15 SIP trunks to the provider, each SIP trunk representing one extension in your company dial plan.

Testing Enviroment
Scenario
This scenario tries to be as simple as possible. The IP - PBX and the phones are all in the same network, having public IP - adresses. The signalling channel will pass through the PBX, the media channel will go from endpoint (phone) to endpoint (provider).

Configuration
Firmware version
All innovaphone devices use V6 SR2 HF7 as firmware.
SIP - Trunk
First of all the SIP Trunk must be configured. Here an example of our Telenor - Trunk. If you want that the Gateway should act as Medialrelay, you must exchange the Gatekeeper Address to an private network address; for example 127.0.0.1. Telenor awaits in the From Header the complete Calling Party Number(CGPN). The default innovaphone setting is to not send the complete CGPN in the FROM - Header, but in the Preffered Identity Header. Change the setting From Header: to CGPN in user part of URI.
Number Mapping
Since the Telenor account does not support DDI, you can map an the account number to an internal extension.
Route Settings
Because Telenor, as most SIP - Providers too, doesn't support overlap sending, you must enable the blockwise sending of the phone number. You can do this by enabling Force enblock in the automatically generated Routes.
The second setting you must check is Interworking(QSIG,SIP). This feature must be enabled to properly relay suplementary 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.
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.
