When the TE60 initiates a SiteCall for more than 30 sites, the system prompts that the number of sites must be less than 30. The SiteCall fails.
The SiteCall function of a terminal is restricted by the length of the call structure. A maximum of 30 sites can join a conference. If more than 30 sites are involved, you are advised to initiate a conference on the platform, or first initiate a conference with 30 sites and then add sites during the conference.
