Testing Enviroment

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)

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 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.

Fax

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.
