Testing Enviroment
Scenario NAT
This scenario describes a setup where the PBX and phones are in a private network. The IP800 must use a stun server, in order to send correct SIP - messages. The IP800 works as media relay, all RTP - streams go through the PBX.

Blind Transfer
When using a blind transfer, the accepts the call and relays it to another callee. This is done by pressing the redial key, typing the desired phone number, followed by the OK key (IP110 & IP230) or the Enter key (IP200).
Tested feature | Result S1 |
---|---|
Call can be transfered | Yes |
Held end hears dialing tone | No |
Broadcast Group & Waiting Queue
From the technical point of view, this features have been tested already. The provider must be able to switch between Music on Hold, announcements and the responding caller. The heavy load of the callswitching is done by the PBX.
Tested feature | Result |
---|---|
Caller can make a call to a Broadcast Group | Yes |
Caller can make a call to a Waiting Queue | Yes |
Announcement if nobody picks up the call | Yes |
Calling Party Number
Here we tested if the provider accepts the phone extension (DDI) and forwards the calling number correctly. Also CGPN suppresion was tested. You can enable CGPN suppresion, directly at the IP200. You can suppress your number by enabling the checkbox "Hide own Number" found under Configuration -> "Registration x" -> Preferences -> "Hide own Number".
Tested feature | Result S1 |
---|---|
CGPN is displayed correctly | Yes |
CGPN can be supressed | No |
Configuration
General Information
Basic Provider Infomation: HFO
- described in Mantis Case: 16505
Firmware version
- IP800: 6.00 dvl-sr2 IP800[07-60600.58]
- IP22: 6.00 dvl-sr1 IP230[07-60600.58]
- IP200: 6.00 dvl-sr1 IP230[07-60600.58]
- IP230: 6.00 dvl-sr1 IP230[07-60600.58]
SIP - Trunk
First of all the SIP Trunk must be configured. Here an example of our HFO - Trunk. If you want that the Gateway should act as Medialrelay, you must exchange the Gatekeeper Address (blue marking) to an private network address (see Media Relay ); for example 127.0.0.1. HFO 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
The complicated part on this issue is the correct mapping of the outgoing and incoming numbers.
Route Settings
Because HFO, 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.
Media Relay
By enabling Media Relay on the PBX, The IP800 will work as an RTP - Proxy, so all RTP Streams will travel through the IP800. This mode poses a much greater load on the PBX, so the number of concurrent calls will be heavy limited.
You may wonder about the usefullness of putting the localhost address as a private network. However you must insert this entry, if the IP800 SIP GW registers at the PBX on localhost interface.
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.
