Hi Steve,
if you could provide more information regarding your setup, you would get guidance from the forum. info such as:
- Type of endpoints with software version
- HD or SD conference
- Type of MCU/TP with software version
- Are participants are on the same LAN or coming from ISDN and internet domain?
- VCS (control and express) software version
- A network diagram of platform
- Is there firewall involved here? (sometimes there are timers enable on firewall that shutsdown the ports)
- is there Bandwidth limitation defined on VCS zones and subzone?
etc. etc.
But in short, there is no time limitation on conferencing units unless you define one there.
regards, Ahmad
