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.

SIP - Trunk

Set an SIP Trunk via Administration/Gateway/Interface/Sip

Important is to set the right port (5082), and a stun server if the setup is behind a Nat router

It is important that on the Trunk Object (in the Pbx ) the flag Outgoing Calls no Name is set.

That means that in the P-Preferred-Identity only the extension will be sent (and so the cgpn will work correctly)

Number Mapping

There is no need to map any cgpn numbers as Tele 2 Austria need s only the extension Number and adds the access number(Trunk number) automatically.

Also for incoming calls the cdpn don't need to be mapped as Tele2 (Austria) sends only the extension to the innovaphone pbx.


Route Settings

Because Tele2 (Austria), 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 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 IP22 to the IP800. When configuring the IP22 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 is setup correctly. You should be able to make call in both directions and send and receive fax messages.
