The table below is regarding the number of SIP sessions supported by each platform for CUBE. If you use the formula which @Vaijanath Sonvane shared you can find the maximum sip trunks supported based on the model which you are going to use. if you look the OLD cube version capacity its much lower than the one below. The capacity of session changes with the version.
Router platform support
CUBE is developed as a component of Cisco IOS XE Software and runs on the platforms listed in Table 2. Maximum trunk session capacity and call processing performance is provided here for the purposes of comparison only. Operational capacity is dependent on various factors, such as call presentation rate, call type (for example, call center or standard IP telephony), transcoding, encryption, and media forking. Figures included in Table 2 are based on simple telephony calls and assume ideal conditions that optimize for either call volume or rate. Updated capacity figures are provided for platforms running IOS XE 17.3.1 or newer releases.
Certain CUBE deployment scenarios may require additional hardware for WAN termination or transcoding. If connected to the IP network through a WAN circuit, CUBE supports all connectivity methods and interface cards supported by the host router platform.
Virtualized CUBE (vCUBE) is available as a licensed feature for the Cisco Cloud Services Router (CSR 1000V), allowing customers to use CUBE features in Network Functions Virtualization (NFV) environments. CUBE features that require direct access to DSPs or voice interfaces are not available with vCUBE.
