Sizing SIP Trunks
As a general rule, most businesses need to reserve phone lines for 1/3 of their employees. A company with 99 employees would need capacity for 33 concurrent calls or 33 virtual call paths. A T1 PRI is delivered in sets of 23 channels. A company making 33 simultaneous calls would need to buy 2 T1 PRIs (46 channels) resulting in an over-provisioning of 13 lines. Often businesses have excess capacity on their data networks. This bandwidth can be used to run some or all of your voice traffic with SIP trunks and dynamic allocation of bandwidth between voice and data. Companies with multiple locations will receive one bill combining minutes and call paths across all sites.
