Is anybody familiar with Digium PRI gateways (G200)?
My two Asterisk boxes communicate with each other via that gateway, with each one connecting to it via a SIP trunk.
Now when I call from one PBX to the other, the Digium prepends a “±” in front of the CallerID.
I see that in the debug of the gateway.
On my phone the CID looks like “?John 4132”.
This invalid character causes all sorts of problems on the other end.
Not sure where to start looking for the fix.
Anybody has ever seen this?
