The server has a hard limit of how many phones can register to it.

> Maximum Number of Registered Devices: 	This parameter specifies the maximum number of devices that can register with Cisco CallManager and is used to limit the overall resource demand. Devices that count toward this limit include: Annunciator devices, H.323 gatekeepers, H.323 phones, H.323 gateways, ICT trunks (gatekeeper or non-gatekeeper-controlled), MGCP CAS trunks, MGCP gateways, MGCP FXS ports (analog ports), MGCP FXO ports, MGCP T1/E1 PRI, media termination points (hardware or software), transcoders, Music on Hold servers (not MOH audio sources), SIP trunks, IP phones, conference bridge devices (hardware or software), legacy Skinny Gateway Control Protocol devices like Cisco Analog Access, and video conference bridges (IP/VC 3540 configured with Skinny Client Control Protocol [SCCP] port). The following devices are NOT counted toward this limit: line appearances (directory numbers), route lists, Remote Destinations and built in bridges.
>  	This is a required field.
>  	Default:  5000
>  	Minimum:  5000
>  	Maximum:  15000
