Hi,

i'm trying to configure a Portech MV-370 working with IPPBX 2820.

I've added a SIP trunk without registration need.

In digit map there is a rule saying that certain numbers (with matched prefixes) must go out through that SIP trunk, else through the backup one.

The outgoing calls work fine. There is a problem with incoming ones. In fact if I try to call the SIM inside Portech, Vigor hangs up the call. This because the Portech sends this SIP message

Code:

To:

Where 192.168.1.254 is Vigor's IP address.

In calls detail log I can see

To = Receiver
From = Mobile Caller Number
Status = Fail

I've tried to force Portech to send destination SIP messages for example to

Code:

extension_number@192.168.1.254

So e.g. if I call the SIM, Vigor receive message from Portech with header

To:<201@192.168.1.254>

But nothing changes.

Some suggestions?

Thanks
