IMS Announcements

IMS Announcements Service

Customer: Major European Mobile Operator

The need: Business Customers required the possibility to provide capabilities for playing a ‘pre-call’ audio announcement to callers calling to specific number or number range. In addition Customer should be able to create and administer recorded announcements.

The solution: Our Team designed, implemented and deployed solution on JAIN SLEE Rhino TAS from Metaswitch. Service implemented two primary use cases:
– playing announcement to specific number or number range
– create announcements: record / listen back / accept or discard announcements
Delivered service exposed also APIs for announcements management.
