25. Bringing you un-matched functionality

26. Investment Protection

27. Unmatched Stability & Performance AudioCodes uses separate processing engines for different gateway functionalities: Embedded CPU for AudioCodes VoIP services DSP farm for offloading media-intensive applications from the CPU Intel-based server for Mediation Server / SBA software Result: AudioCodes provides better performance and better stability Mediant 1000

28. Worldwide PSTN Homologations Communications Server “14” enables more IP-PBX-oriented features Survivable Branch Appliances can be connected directly to the PSTN PSTN homologations become mandatory !!! Some of the competitors are new to the PSTN world AudioCodes Gateways have been deployed in over 100 countries

29. Interoperability Interoperability with numerous TDM PBXs Interoperability with non Microsoft-certified IP-PBXs Quick time-to-market No need to invest in the existing equipment Microsoft UC Network Non-Certified IP-PBXs Other SIP IP-PBX Microsoft SIP Media Gateway More… IP Phones Office Communications Server 2007 OC Client E1/T1/BRI/FXO PBX

31. Active Directory Support Enables phased and easy migration from TDM to UC Call routing based on Active Directory information (to TDM PBX, OCS, or alternative mobile phone numbers) Enabling redundancy in case of any subsystem failure (routing the call to alternative numbers) PSTN Office Communications Server 2007 OC Client Active Directory LDAP John Ben

32. Direct connectivity for legacy analog devices (Phones, Fax and Modem) Microsoft Exchange Server 2010 stopped supporting Fax termination On the other hand, Communications Server “14” supports direct analog phones connectivity for the first time Questions asked: How can we terminate fax calls? How can we connect analog phones? AudioCodes analog ports support the connection of analog devices and the intelligent routing of fax/modem calls to physical fax machines / modems or to fax servers
