Connecting with Dect Phones

This use case will show you hoe to extend the capabilities of your legacy PBX with DECT phones using your tsandar FXS or BRI ports in the PBX one Vega 50 and a third party DECT IP base station

This is a very cost effectuve way to enable, for example, in a factory envronment, or in an hospital to take advantage of DECT technology for wireless phones assigned to in move personnel (around the building or in a plant or large warehouse) and integrate them as plain extensions of a legacy PBX that has no DECT support and is far away from the location where the etensions are needed

Open

PBX<-- (BRI/FXS)-->VEGA50<--(SIP)-->BASE-STATION<--(DECT)-->Hand Sets

I am assuming for simplicity that each BRI/FXS port on the PBX will be associated  to 1 DECT extension.

To do this you will need:

For this example, and as there is no IP PBX in the show, we will be using ENP in Stand Alone mode (Using 5060  port for media gateway and 6060 for ENP):

Create one registration instance for each one of the of the DECT phones.

You will need to define on the Base Extension the identities to register in the vega ENP.

Open

Just to illustrate what is needed in the Base extension here is an example of the configuration screen of a KWS6000 Server. The highlighted fields must be populated with the identities and credentials defined in the previous point.

Realm for ENP will be the Vega IP address (i.e. 192.168.200.20):

To keep consistency, keep ITSP Proxy pointing and enabled to Vega IP address: 

Make sure Trunk Gateway on ENP is properly enabled as this:

Make sure ENP has enabled and configured the Trunk Gateway, so any (TEL:*) outbound call will always be sent to Trunk gateway ID 1 (defined in previous point)

You need to create a SIP Profile pointing from the Media Gateway side of the Vega to the ENP Proxy side (Vega IP is 192.168.200.20 in this example):  

And

Also, disable SIP registrar on this profile:

Now, on the Dial Plan, you will need (TO PSTN: meaning  to the PBX, and to SIP: menaing to DECT Phone via DEC Server like this:  

So, To_PBX_via_BRI should containg this rule, asuming extensions are 101, 102, 103, …. Etc)

Source:                IF:9901, TELC:1<..>,TEL:<.*>

Destination:       IF:03<1>,TEL:<2>

This rule, will get the calls coming from the ENP and send them to the appropriate BRI/FXS interface to the PBX based on the extension number defined on the DECT Server/Base Station which is dialing.

Then, To_DECT_vis_SIP should contain his rule, to rote the call coming from the PBX to the appropriate DECT extension based on the BRI port receiving the call:

Source:                IF:03<..>

Destination:       IF:9901,TEL:1<1>

At this point it should work.
