Operational Notes
Be aware of the following limitations in this release:
• AltiGen IP phones – AltiGen IP phones IP-705, IP-710, and IP-720 must all be upgraded for firmware
version 2xA8 before you upgrade to MAXCS 7.5.
• Clients – You must upgrade all of the MAXCS client applications on a desktop before the agent uses any of
those applications.
• When a Polycom phone is used and the voice stream goes direct, SIP tie-trunks need to use RFC2833
instead of SIP INFO.
• To log into VRManager, right-click VRM Admin and click Run as Administrator.
• If a workgroup agent use a Polycom phone, Single Call Handling will be automatically be enabled,
regardless of the workgroup’s Intra Group Call Distribution setting.
• When a Polycom user places a call on hold via a MAXCS client, no dial tone will be played.
• With AltiGen SIP trunks, you must use 11-digit numbers when configuring DNIS routing.
Software Upgrade Path
MAXCS 7.5 supports ACM only. ACC Agent seats will automatically be upgraded to ACM Agent seats. No
additional SA will be incurred during the upgrade process. Note that ACM SA charges, instead of ACC, will be used
for the next SA renewal. For details on SA renewal, contact your AltiGen representative.
This release supports Softswitch ONLY. Hardware chassis support will be added in a later update.
The diagram on the next page shows the software upgrade paths (not license registration) to convert older
