Hi,

Asterisk PBX connected to NEC (Model Number not available)ISDN signalling used qsig/euroisdn.
While calling from Caller X ->  PRI A (E1 PSTN) to DID Route to PRI B (NEC) -> NEC extension rings but no ringback on  Caller X but can talk if extension picks up the call.

It's looks like same issue mentioned in https://issues.asterisk.org/jira/browse/ASTERISK-14397
but in this case I can talk if the NEC extension picks up, only issue is no ringback tone for the external callers.
Internal Xlite/Eyebeam has ringback tone but Hard extensions cannot hear ringback tone.

I have had used/changed most available parameters for PRI.
