I have a customer with a Telrad 2464, wanting to add a PC Based Voice Mail. Their main concern is ensuring the system can light their message waiting lamps. To complicate matters, the client does not have any supporting documentation for the system. Can anyone assist me with the code information to activate the MWL? Does the Telrad 2464 support in-band signaling? Unfortunately, I know nothing of the Telrad 2464 system. I appreciate any assistance.

The Telrad 2464 will support message lights.
The 4button set has a fixed button with light, the bigger sets have a fixed button with a led arrow.You will need a OPS card to hook your voice mail to.
Hope this helps
