Problems transferring calls

[sostek]

Ok - I have two Definity switches connected via DCS over a PRI circuit.

Person dials our Archives division. Their service is attached to Switch A via an MCK over PRI. They try to transfer a call to Switch B (DCS) and the call goes but after a few seconds it drops. Interestingly if the person at Archives transfers it to an extension on Switch A it works.

This leads me to believe that supervision is dropping once the call gets onto the DCS trunk.

Anyone else seen this problem and know how to fix it? Switch A is an older G3iV6, whereas Switch B is a Prologix G3iV11.

I figured it out. In the trunk definition for Archives on Switch A, I had to set disconnect supervision for inward calls.

The thing that tipped it I realized I was doing a trunk to trunk transfer (Normal to DCS) and if supervision wasn't passed along, it'd disconnect within six seconds.
