CALLUP Announces New Version of Its SMS Center (SMSC) that Uses Apache™ Cassandra™ NoSQL Distributed Database

Rosh Ha’ayin Israel, August 7,  2017. CALLUP, a global provider of Value Added Services (VAS) and Mobile Device Management (MDM) solutions for the telecom industry, today announced a new version of the company’s Short Message Service Center (SMSC), a critical element in carriers’ networks that stores, forwards, converts and delivers SMS messages. The new version – CALLUP SMSC 5.0 – uses Apache™ Cassandra™, a highly-performant Big Data distributed database. Apache Cassandra powers at CALLUP SMSC 5.0 an integral data warehouse for SMS logs, capable of storing tens of thousands of records per second and allowing the search of SMS records in milliseconds, even if there are hundreds of millions of records.

Apache Cassandra is an Open Source, "NoSQL" distributed database management system designed to handle large amounts of data across many servers quickly and reliably, whether running in the Cloud or in a hybrid data store.

“We are very pleased to join numerous companies, in many industries, that power demanding applications with Apache Cassandra,” said Alon Roth, CALLUP’s CEO.  “The combination of CALLUP SMSC and Apache Cassandra results in a most advanced SMS center, with unparalleled performance which can help carriers enter a new era in SMS management.”

CALLUP SMSC is a feature-rich, high-performance and high quality SMSC platform. Utilizing state-of-the-art technology, it offers high capacity traffic and supports all network messaging technologies – including GSM MAP, SIP/IMS and IS-41. CALLUP SMSC is protected from overload, by constantly measuring the success rates, response times from other elements (STPs, HLRs etc.), and other algorithms, to maintain the best service level possible even under high loads.

SMSC 5.0 includes an advanced dashboard providing quick insights on the status and performance of the SMSC. Other improvements implemented in the messaging gateways provide higher throughput per node, making the system capable of managing tens of thousands of transactions per seconds (TPS) with minimal hardware requirements.

CALLUP SMSC enhances SMS security, including anti-spam and anti-spoof modules. SMSC prevents hackers from spamming subscribers, by checking the validity of their originating address with the VLR (Visitor Location Register) records in the HLR (Home Location Register). VLR/MSC (Mobile Switching Center) blacklists for override can be configured, as well as IMSI (International Mobile Subscriber Identity) ranges and target addresses.


Founded in 1999, CALLUP provides Value Added Services (VAS) and Mobile Device Management (MDM) Solutions. CALLUP is a subsidiary of the One1 Group, headquartered in Israel and listed on the Tel Aviv Stock Exchange (TASE: ONE).
