YETI. What is it?

How it works

Web interface

• Easy to use WEB 2.0 interface

• Authentication via LDAP

• Management and Monitoring

• Rating and Invoicing

• Full data auditing and versioning

Statistics and reports

• Short-term realtime statistics for each route and gateway allows to detect quality changes for this entities
  

• Interface to create custom reports based on CDRs analysis

• Automatic reports generation and mailing

Billing

• Real-time prepaid, postpaid and wholesale service

• Detects and prevents potential fraudulent activity

• Automatically disconnects calls to prevent balance overdrafts

• Manual/automatic Invoice generation

• PDF/ODT/CSV/XLS  traffic detalisation documents

CDR

• Asynchronous CDRs writing. Allows to provide high performance and stability of recording
• CDRs writing does not affect on signaling traffic or processing performance
• Customer specified/adaptive CDR Format

Ensuring compatibility and SIP normalization

• Disconnect codes translation

• DTMF translation (both ways between SIP INFO and rtpevent) and normalization

• Normalization for SIP and SDP

• Additional features to handle non-standard SIP implementations

Routing

Authorization / routing capabilities

• Authorization by IP, SRC prefix, DST prefix, POP, SIP URI domain, custom SIP header

• Flexible billing and routing rules for authorized traffic

• Various routing algorithms. Load Balancing

• Black/white lists on any stage of routing

• Channels limitations

• Simultaneous calls limitation for any entity

• Local Number Portability. Requesting LNP databases is performed using SIP or HTTP REST API

Media Processing

• Transcoding between following codecs: g711(alaw, ulaw), g723.1, iLBC, speex, GSM, G726, G721, OPUS*

• Flexible configuration of the codecs negotiation

• Effective NAT traversal using comedia (symmetric rtp) and rtp ping

• Fax transmission through T.38 relay and inband g711

*ready for testing

Failover and rerouting

• DNS SRV for SIP signaling

• Geo-clustering and redundancy

• Disconnect codes or ringing timeout rerouting

• Flexible routing/rerouting rules for each termination gateway

Geo-distributed systems and clustering

Geo-distributed high availability cluster installation supports:

*connection failures between components

• Horizontal scalability for all components
• Zero-downtime upgrade
• Error-free* call processing
• Geo-POP based termination
• Traffic managing without active calls affects.
