Howto:Analog Trunk (FXO) with Level One 4 Port FXO Gateway

Innovaphone Compatibility Test Report

This test report describes how to connect an analog Trunk line (FX0) , analog Pstn Line with innovaphone pbx.

For connecting an analog Trunk Line you need to use a third party product - here tested with Level One VOI-8003 4FXS +4FXO Voip Gateway.

The Level One supports sip and h.323 protocol simultaneous , same as innovaphone.

H.323 advantage and disadvantage

You can directly connect this third party Gateway to the innovaphone Pbx (with the H.323 protocol)

Because the Level One does not support H.323 EFC - it is impossible to make call hold or call transfer.

With the H.323 Protocol you do not need an extra Gatekeeper license - connect directly to the Trunk Object in the Pbx.

It is also possible to dial from an innovaphone phone (connected at the innovaphone pbx) the whole number at once - no need to wait for the analog line tone (dial tone)

Sip advantage and disadvantage

We recommend to connect the Level One with the Sip protocol ,because then it will work hold and transfer.

Connecting with Sip you need a Gatekeeper/Registrar license because with sip (implementation in the level one) you can´t dial the whole number at once to the analog Trunk.

Therefore you will need a special route to the Level One in the Routing table- then it will be possible to dial the whole number at once.

Level One VOI 8003

Information:

• Software Version Web UI version 2.0
• Hardware version 1.0

innovaphone gateway/pbx

This information applies to

• all PBX Platforms

6.00 build 07-606007201 (hf4)

H.323 configuration- not recommended

With this configuration you can dial the whole number at once . you don´t have to wait for the analog dial tone.

innovaphone configuration

In the innovaphone Pbx you only need to configure a Trunk Object where you register the Level One Gateway

Level One configuration

Register with H.323 to the innovaphone Pbx

Gatekeeper- ip address of the innovaphone pbx

H.323 id and e.164 - Long Name and Number from the Trunk Object

Line settings - Hot Line must be enabled

For Codec settings go to routing setup / routing profile

Routing from analog Trunk Line (FXo Port) to innovaphone pbx

The area code must be hl1 and the strip 3 digits - because otherwise the digits hl1 will be created and send to the innovaphone pbx by the level one gateway.

As prefix put here any number what should ring in the innovaphone pbx - this number will be sent to the innovaphone pbx.

Routing from innovaphone Pbx to analog Trunk

you need to configure an area code- here it is 0 - that means you need to dial an extra 0 to get the Fxo Line 1

Known Problems

The Level One does not support Overlap sending - so you need to force the Ip Phones to send the number with enblock

Or maybe take an Gateway Object instead of an Trunk Object and enable enblock on the Gateway Object.

Also you need to dial the area code (voip call in) from the Level One- so in this configuration you need to dial 2 times 0 - one 0 for the Trunk Object and one 0 for the Level One.

If you take an Gateway Object -the one 0 you dial will be also send to the Level One Gateway .

Any kind of Transfer and Hold is not working.

Sip configuration

To connect the Level One Fxo Gateway with Sip is the recommended solution.

innovaphone configuration

You need a Gatekeeper/registrar License

Go to gateway/administration/voip and create a new gateway

Configure a route to the Level One

For the special routing entry you need at least this version 07-60711 in the pbx/gateway

Number out is here a 0 - you can take any digit this is for the analog trunk assignment.

Then you configure a " ^ " this indicates an Delay for one second , then the rest of the number will be dialed in dtmf with 300msec delay between every digit.

So in this configuration you do not need to dial a extra 0 for the Level One .

For the incoming route make a default route into the pbx (from the gw where the Level One is connected to the Gateway where your Trunk Object is connected)

Level One configuration

Registration

As sip proxy take the innovaphone pbx/Gateway

As registration take a number - here the 0

The Voip call in and Voip call out settings are the same as in the h.323 config - see above.
