Hi
I have tried connecting a OBI110 to a NEC XN120 pbx via the line port to an internal extension, so that when a call comes in on the ISDN, the PBX routes it the OBI110 which then sends the call to a sip address onto a OBI100.
Now when a call comes in, the obi will ring, but it disconnects every 3 seconds and then rings again. Also, I cannot answer the call.
I think it may have to do with the voltage etc.
Does anyone have any experience?
