According to the study, Mobicent SIP Servlets (MSS) "adapts dynamically to failures through lazy replication and selection of new replication buddies. This allows MSS to restore protection to machine failures and rack failures automatically even without restarting failed servers in the same replication group. Therefore, the odds of session loss in MSS are lower than in OCCAS or WAS."
Brazilian mobile provider Algar Telecom in Brazil is in the first rank of companies deploying these innovations currently. They recently teamed with middleware telecom developers at Austin, TX-based Telestax to come up with a rapid solution for providing robust telecom services across Brazil. Despite rapid growth and infrastructure challenges, Algar has deployed an interactive voice response service capable of handling 120,000 calls per day. Their messaging service now delivers more than 500,000 SMS messages each day.
