Message Waiting Indication Voltage 2

[KCFLHRC]

Does anyone know what the MW Indication Voltage is on the Phone 16 and 30 modules? I need 90 VDC to light the light on existing analog phones.

Thanks

Message waiting lamps

IP Office uses message waiting indication (MWI) to set a lamp or other indication on phones when a new message has been left for the user, either in a personal voice mailbox or in a group mailbox or call back message. After the system plays the message, it turns the lamp off.

All digital and IP phones have in-built message waiting lamps. Avaya one-X® Portal for IP Office provides message waiting indication on screen.
For analog phones, IP Office provides a variety of analog message waiting indication (MWI) methods:

51 V stepped
81 V
101 V
Line reversal

The system administrator or installer selects the MWI method using IP Office Manager during configuration to match the properties of the analog phones.
Note
101V signaling is only available on IP500 phone cards and expansion modules.

Thank you, sounds like we are covered no matter what with all those choices. We are proposing replacing an Old Nortel Option 11 with IPO and they would like to keep the Guest Room Phones as is in the Hotel. They have a 90 VDC MW light.
