When integrating via SIP the ShoreTel and Sonexis devices should reside on the same LAN segment in a network environment configured for prioritization of voice traffic (DSCP 46). The Sonexis ConferenceManager supports standard SIP integration using RFC 2833 or SIP INFO for DTMF relay. Audio is supported via RTP 20ms payload using ports 11000-13000 UDP. The Sonexis ConferenceManager supports Ethernet connectivity at 1000 or 100 Mbs. By default the Network Interface Cards are configured to auto-negotiate for speed and duplex. For SIP integration, a Shoregear 60/12 or similar is required. The Sonexis ConferenceManager will support up to 120 simultaneous connections with 1- 8 DSP AC-1 card, or up to 200 simultaneous connections with 1- 12 DSP AC-1 card. For integrations above 200 ports, systems are cascaded with the appropriate AC-1 configuration. For traditional TDM integration, the Sonexis ConferenceManager supports CAS (channel associated signaling) via E&M Wink as well as PRI/ISDN integration via NI2, 5ESS, 4ESS, DMS100, DMS250. The ConferenceManager supports D4/AMI and ESF/B8ZS. For integrations up to 96 ports, 1- 8 DSP AC-1 card is required (4 RJ48 ports per card). For integrations from 97 up to 192 ports, 1- 8 DSP AC-1 and 1- 12 DSP AC-1 are required (4 RJ48 ports per card). For integrations above 192 ports, systems are cascaded with the appropriate AC-1 configuration. 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 5 - Requirements, Certification and Limitations The Sonexis ConferenceManager is a self contained system requiring no additional hardware or software to operate.

Port 80 is required for Web functionality; port 8097 is required for administrative management. The ShoreTel hardware requirements will depend on the type of integration selected (SIP or TDM). For SIP integrations the Shoregear 60/12 or similar will be required (as well as the associated SIP licensing) to provide SIP trunking. For TDM integrations, one Shoregear T1 module is required for each T1 span, for example a 48 port Sonexis system, 2 ShoreGear T1 switches will be required. 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 12 - ShoreTel Configuration Be sure the system is NOT set to use RTP port 5004 for RTP. Uncheck the box if it is checked-THIS REQUIRES A REBOOT OF ALL SHORETEL EQUIPMENT, EVERY PHONE, EVERY SWITCH, SHOREWARE DIRECTOR, ETC. This is configured on the CALL CONTROL/OPTIONS screen. Also, be sure the Sonexis is plugged directly into the same LAN switch as the ShoreTel as you want the VOIP traffic between the two systems isolated from the rest of the network. For best audio quality be sure the switch supports prioritization via DSCP. 1 Shoretel SIP license is required for each Sonexis Audio Port. Obtain a license from your ShoreTel reseller for the required SIP ports. - i.e. if you have 48 audio ports on the ConferenceManager, you will need 48 SIP ports on the ShoreTel SIP trunk to the ConferenceManager. You will need to create/configure a SIP trunk group on the ShoreTel. Set the “teleworkers” checkbox. Sonexis supports either “SIP info for G.711 DTMF Signaling” or RFC 2833(which is the default on Shoretel). Note: Enabling the “Teleworkers” parameter causes the ShoreTel system to utilize 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 13 - the Inter-Site Codec. Mark the checkbox for “Tandem Trunking” this will allow trunk to trunk calls, ie calls that come in via T1 to get routed over the SIP trunk to the Sonexis. This feature is combined with a “user group”, be sure you associate a group that has trunk to trunk privileges. Fill in the “number of digits from CO” field, typically 4 (how many digits are you going to pass to the Sonexis?). Also, check the “outbound” check box and configure an access code (ie the number a person would dial to get that trunk group- 9 is most likely already taken for an outside line, perhaps 8 is free). You must also put in the area code. Save the trunk group. For further information please refer to ShoreTel’s Planning and Installation Guide. From the same trunk group screen, configure the "off system extension" to be the ext/DNIS you want to use for the Conferencing System. For example, if you want your outside callers to dial 555-555-5555 to get to the ConferenceManager, then you need to configure 5555 as the ext for "off system ext". This is configured via a button at the very bottom of the “sip trunk group edit” screen. It asks for a range, if you‟re using a single ext just type that in twice, ie 5555 to 5555. This is only a recommendation to ease you in extension planning; it’s not necessary to match the DNIS / DID number to the Off System Extension (OSE). 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 14 - 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 15 - You will also need to add this EXT to the DNIS MAP on your inbound T1 or Analog lines so that the ShoreTel will recognize the DNIS and route the call to the Sonexis (depending on whether you use 3 or 4 digit extensions and what your phone company passes for DNIS digits). From the T1 and/or Analog trunk group edit screen, select EDIT DNIS MAP. Put the “received digits” in the first field (what does the phone company pass, ie last 4 of the phone number associated with the Sonexis 617-458-5800), put the whole “dialed number” in the next field ie (617) 458-5800, then click the “off system” radio button and type the ext you configured in “off system ext” on the SIP trunk group. Now click “add record” 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 16 - You will then need to configure individual trunks in the SIP trunk group you created that point at the IP of the ConferenceManager. Choose the “individual trunks” link in the “trunks” section, then “add new trunk” and choose the SIP trunk group you created in step 4 from the drop down list. Put in the number of trunks (same as number of audio ports on the Sonexis) and the IP of the Sonexis in the “Use IP Address” field. Choose the appropriate switch in the drop down list, this will be the switch with the SIP capability on it ie 60/12.

Roughly 85K/port. 10 ports would require 850K of bandwidth. This feature will PREVENT calls if you exceed the bandwidth and will play a message to the caller that says “I‟m sorry the network is busy; please try your call again later”. If you hear this message, you have allocated too little bandwidth. If you have configured the Sonexis Conference Manager product for TDM use, you will need to configure the ShoreGear T1. Following is an example of a ShoreGear T1 configured for PRI, be sure to also configure the appropriate PRI (or Digital Wink Start) Trunk Group. Please refer to ShoreTel’s Administration Guide for more information on configuring ShoreGear T1s. 960 Stewart Drive Sunnyvale, CA 94085 USA Phone +1.408.331.3300 +1.877.80SHORE Fax +1.408.331.3333 www.ShoreTel.com - 18 - Sonexis Configuration Unbox the Sonexis ConferenceManager.
