asterisk users - Apr 2006 - MWI in multi-PBX setup

Has anyone tried to set Message Waiting Indicators up when public network
access and voicemail service are managed by an Asterisk server TDM-connected
to a legacy PBX serving analog and digital phones ?

For instance:

Location 1:
- 200 users on a legacy PBX
- among those users, 50 have access to voicemail service
- TDM trunk to Location 2

Location 2:
- 100 users on Asterisk
- PSTN access
- TDM trunk to Location 1

Does it make any sense to service all 300 users with MWI from the * server ?
How does it work ?
How could you light legacy PBX phones from Astrisk voicemail ?

Regards

It really depends on the PBX in use. Avaya uses DTMF tones to light
the MWI, you can find examples on the wiki on how to do it. In which
case you shouldn't have any problem doing it.
Most of the bigger phone systems I have worked with allow the same
thru simple DTMF tones.
