Dialogic Media Gateway
Configuration Note 27 of 32

Audio Path
Always-In
Audio section of SIP Line in IA
The Dialogic Media Gateways don’t respond to all Dynamic Audio requests properly. For
MIC, this is not a system requirement, so it is best to leave the audio Always In.
Server Parameter Configuration:
For MWI to properly function, the UM_MessageLight handler will look for an “@” in the MWI
Address specified on the MIC user through Web Admin.
If there is no @, which is most often the case, then the handler looks for a Server
Parameter called ‘MWIIPAddress’. This parameter needs to be created on each MIC server,
and should contain the IP Address of the Media Gateway responsible for processing MWI
requests (port can also be specified if not using 5060. Ex: 1.1.1.1:5061).
Please note, that for any given MIC cluster, only one Dialogic Media Gateway can act as the
MWI processing device. To make changes to this will require handler customizations in
UM_MessageLight.
8 PBX Integrations Tested with MIC
The following test cases were tested in the Dialogic PBX labs during an integration test that
consisted of six (6) different PBX types, and eight (8) different integration methodologies.
The tested PBXs were:
• Nortel CS-1000M (Succession) (Q.SIG & Digital Set Emulation)
• Mitel 3300 (Q.SIG)
• Mitel SX-2000 (Digital Set Emulation)
• Avaya S8500 (Q.SIG & Digital Set Emulation)
• Siemens HiPath 4000 (Q.SIG)
• NEC 2000 IVS2 (Digital Station)
Test cases:
1. Leave a message for a subscriber, verify MWI goes ON)
2. Retrieve message and save/delete it, verify MWI goes (OFF)
3. Call a PBX extension, Ring No Answer, verify proper mailbox is reached when call is
forwarded to Voicemail
4. Call a PBX extension, Ring No Answer, verify proper mailbox is reached. Zero out to
a PBX extension. Let that call Ring No Answer. Verify that the call goes into the
Originally Called Mailbox. NEW TEST
5. Call a PBX extension that is forwarded to another PBX extension, Ring No Answer,
verify that the Originally Called Mailbox is the one that answers
6. Call an Attendant menu that transfers the call, verify IP and TDM resources released
from MIC and from the Dialogic Media Gateway.
