Interesting set of AudioCodes guides

AudioCodes has released a set of guides describing Advanced Topologies for OCS 2007 and Exchange 2007. There are several interesting scenarios including -

  • Cisco Call Manager connectivity to Office Communications Server 2007 and Exchange Server 2007
  • Single gateway for Office Communications Server 2007 and Exchange Server 2007
  • Asterisk IP-PBX connectivity to Office Communications Server 2007 and Exchange Server 2007
  • Enabling fax, modem and auxiliary devices for Office Communications Server 2007
  • PBX reduced trunk solution for Office Communications Server 2007
  • SIP trunking solution for Office Communications Server 2007

The last one about SIP Trunking looks interesting to some of my customers, it describes the following scenario -

“OCA” is a small, but growing retailer of outdoor clothing and apparel company located in New-Jersey, USA. OCA has a deployed Office Communications Server 2007 in its private network for enhanced communication within the company.
OCA decided to offer its employees Enterprise voice and to connect the company to the PSTN using a SIP trunk. OCA's major market is located in Japan and therefore, decided to select two ITSPs – TelIP located in USA and IPConnect located in Japan – for providing a SIP trunking solution. In addition, since OCA's Internet infrastructure frequently experienced interruption and loss of connection, the company decided to implement a telephony backup solution whereby in case of a connection failure with the SIP trunks, the calls are rerouted to the USA PSTN through a traditional T1 connection.
