The AWC key is what you're probably looking for. But beware, this is lifted straight from the Symposium, M1/Succession 1000, and Voice Processing Guide, pub. 297-2183-909 rel 5.0, dated April '04:

Unsupported phoneset keys
ACD Waiting Calls key/lamp
The ACD Waiting Calls (AWC) key/lamp is not supported in Symposium Call Center Server to indicate skillset information. Any AWC key/lamp defined on an agent’s or supervisor’s phoneset indicates information on the ACD-DN for the phoneset, as configured on the switch.

It will only indicate how many calls are in the agents' actual queue, probably more useful in ACD-C2. If that's what you need then go for it. In LD 23 set the queue thresholds:
CWTH - # of callers in Q - Lights the lamp solid
BYTH - # of callers in Q - Lamp flashes slow, prevents OVF from another Q
OVTH - # of callers in Q - Lamp flashes fast, prevents OVF from other Q, starts looking for another Q if you have designated one. a good starting point might be:
CWTH - 1
BYTH - 3
OVTH - 5
Once aginbg, since you are using Symposium, these may not have the effect you want, but try it.
