Hi,
This is a bit of an odd one.
It's taken us a while to work out the situation.
It's an IP500 V2 6.1.12, all VOIP phones 1600 series.
The trunks are ISDN 30's (x2).
G711 now being used, but was the same on G729.
When we use the VM pro to record incoming external calls, we get a drop in volume of the far end.
It's only when there is more than about 5 calls being recorded.
Only seems to effect the users being recorded.
It's not a very busy switch, never more than 15 calls on the go.
There's 20 VM channels, never seen congestion.
64 VCM channels.
There's a small amount of packet loss 3 - 9%, but this doesn't seem to change when recording or not.
The calls are not choppy or dropping out, they just go quiet. Sometimes fading in and out.
Any ideas??
Thanks as always...
