Hello carnick36,
welcome to the Polycom Community.
It would be really useful if you could tell us what SIP switch you are planning to use with this.
I am not aware of a Parameter to disable the caller ID but you could play with the voIpProt.SIP.CID.sourcePreference parameter.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
