SV9100 system with analog CO trunks. There are 8 trunks, on 2 line cards.

Occasionally, when a call is parked, the caller will hear the page announcement. Clearly enough to tell what is said. It has happened to me, but I neglected to find out the trunk that I was on.

The 9100 outputs the page to to a multi line port which has a PGD2 connected to it. This goes to page zone 1 and zone 2.

I thought about swapping line card 1 and 2 around, but I'm pretty sure the incoming call this morning was on trunk 1 - 4, as they weren't very busy today. Last summer I replaced the first line card (trunks 1 - 4) because there was a problem with one of the positions. This page/park trouble has been happening since before the line card replacement, so unlikely it is a line card. ??

Perhaps the digital station card that the PGD2 is on?

Thanks.
