Introduction This guide describes the enhancements that have been added in MaxCS Release 7.5. These features are fully documented in the MAXCS 7.5 documentation. Related documentation includes: • MAXCS 7.5 Upgrade Guidelines – Describes how to upgrade to release 7.5 from older versions of MAXCS • MAXCS 7.5 Polycom Configuration Guide – Explains how to configure Polycom phones for release 7.

• The Persistent TLS connection for SIP tie-trunk is no longer supported • Redundancy is no longer supported • Multiple gateway Softswitch is not supported Additional Changes Please note the following additional changes in Release 7.5: • AltiGen Phone Group Paging uses a SIP Tie Trunk channel in this release. • If Polycom phones are used, you must select RFC 2833 for the DTMF Transport field in the Codec Profile assigned to the SIP tie-trunk.
• SightMax Seat license (MAXCS-SIGHTMAX-xx) – This license supports integration with SightMax Enterprise Edition software (for instructions on configuring and using the MaxCS SightMax Integration service, refer to the MAXCS 7.5 SightMax Configuration Guide (when available). Codec Enhancements Codec enhancements in Release 7.5 include the following features: • G.722 Supported Devices/Interfaces • G.722 License Information • G.722 in HMCP Board Configuration • G.
G.722 License Information The G.722 codec is enabled using the Combo codec license. The number of total codecs is shown in the License Information panel (for Softswitch and Cloud deployments). You will see the G.722 codec choice in various places throughout MaxAdministrator, wherever you see the other codec choices for Softswitch and Cloud deployments. G.722 in HMCP Board Configuration In Release 7.5, the G.
Managing Codec Priority The Enterprise Manager Codec tab has been updated. You’ll now see a list of available and selected codecs. Click the Add and Remove buttons to move codecs from one list to the other, as needed. During codec negotiation, the highest-priority codec that the receiving end supports will be used. Therefore, you should sort the Selected Codec list by priority, from top to bottom. Use the Up and Down buttons to do this.
Managing IP Network Bandwidth Also in Enterprise Manager, the Servers > IP Networks tab has been updated. Instead of specifying the maximum number of sessions per each codec, as in previous releases, in release 7.5 you specify the maximum number of sessions per bandwidth range. The actual network bandwidth required for the bit rate range is used for the bandwidth calculation. 33 to 64 Kbps bit rate is translated into 100Kbps network bandwidth, which includes LAN and IP/UDP/RTP header overhead.
Codec Negotiation The logic for negotiating codec capabilities varies for various types of connection. Codec Negotiation – Server to Client With a server-to-client connection, the highest priority codec in the server’s codec list that is supported by the client will be assigned. Following is an example of a typical setting for SIP devices on a LAN: G.722, then G.711 Mu-Law. This hierarchy allows Polycom phones and the AltiGen IP-805 phone to connect via G.722. AltiGen IP phones will connect with G.711.
Codec Upgrades As mentioned earlier, Release 7.5 offers more flexible codec preference settings than earlier releases. Enterprise Manager converts your existing codec configuration to new 7.5 codec profile settings. Because of this, after you upgrade to release 7.5, you should review the converted codec settings and adjust them as needed. The following table details how codec profiles are converted during the upgrade process. Original Codec Profile Converted MAXCS 7.5 Selected Codec Profile G.
Codec Preference – Incoming Calls When the Codec Preference feature is enabled, the system uses the following logic for handling incoming calls, based upon the content of the first SIP INVITE request. Preferred Codec is G.729 First SIP INVITE Request Content Codec Used for Call SIP Trunk supports G.729 The IP Codec table of Enterprise Manager is ignored. The system uses codec G.729 to negotiate with the endpoint. SIP Trunk does not support G.729 No codec is enforced. Preferred Codec is G.
Preferred Codec is G.711 Mu-Law First SIP INVITE Request Codec Used for Call Supports G.711 The IP Codec table of Enterprise Manager is ignored. The system uses codec G.711 to negotiate with the endpoint. Does not support G.711 No codec is enforced. If the source extension is enabled for Fax-Over-IP (FoIP), then no codec is enforced.
• Improved system performance, because no MIPS is required for codec processing • Improved voice quality, because no distortion is introduced by additional compressed codecs • Reduced voice latency, because it eliminates the delay introduced by codec and jitter buffer processing In addition to benefits to direct calls, pass-through applies during call recording, silent monitoring, and coaching. Pass-through is enabled by default. To disable it, modify the statement in this file: ..
• Forward All Calls – forwarding target must be an FoIP extension or FoIP hunt group • Busy Call Handling – forwarding target must be an FoIP extension or FoIP hunt group To configure an extension as a FoIP extension, 1. In MAXCS Administrator, select PBX > Extension Configuration. 2. Select the extension on the left. 3. On the right, in the IP Extension group, check Enable Fax-Over-IP. Once Fax-Over-IP has been enabled, all outbound calls from this IP extension will use G.
FoIP Hunt Group MAXCS 7.5 supports FoIP Hunt groups; there is no specific configuration type for such hunt groups. In a FoIP hunt group, all group members must be FoIP extensions. Group queuing is not supported.
SNMP traps are logged in text files: SNMP_Altiserv.txt, SNMP_DinaProxy.txt, SNMP_GlobalAppearance.txt, and SNMP_SPServ.txt. Additional Enhancements MAXCS 7.5 includes a few additional enhancements. • The HMCP Certification tool has been expanded • The Block Unauthorized SIP Invite feature now has a checkbox within MAXCS Administrator • A Version number field has been added for tighter SightMax integration. HMCP Certification Tool Enhancements MAXCS 7.
IP extensions for the following devices are added to the Trusted SIP Device list automatically: • AltiGen IP Phone • 3rd Party SIP Device • IPTalk To enable protection, 1. In MAXCS Administrator, open Boards view and double-click SIPSP. 2. Select Board Configuration > Advanced Configuration. 3. Check Block Unauthorized SIP Invite and click OK. SightMax Version Setting MaxCS 7.5 includes a new field for the SightMax Integration application.
Client Enhancements MaxAgent and MaxCommunicator have new settings, to better support Polycom phones. Handling Calls via Clients (Advanced License required, VVX only) Users can configure MaxAgent and MaxCommunicator to answer or place calls via your Polycom phone. In MaxAgent and MaxCommunicator, the setting is under Configuration > Extension: Use Polycom phone to make or answer calls.
