USR® telephony accessories and line sharing devices provide simple solutions for line consolidation while maintaining secure communications to remote telecom and network assets. USR's Call Directors automatically route calls over a single telephone line allowing continued monthly cost savings for significant ROI in 3 months or less.

Line Sharing Devices provide secure access to remote locations making it ideal for utility meter reading, HVAC control monitoring, substation communications, modem polling, fuel tank monitoring, service port access, SCADA interrogation, and general remote site management. 

Our Call Director Pro industrial grade line also provides additional security features including Security Access Codes, Caller ID "Store & Forward", multiple line seizure ports, remote programming, and data disruption protection effectively acting as a telephony firewall and dial-up gateway.
