The firmware of the phones and pbx will be continuously improved.
Please make sure to have the installation of pbx-system and phones
always on the latest sw-releases.

The phones can be updated via several options:
• Centrally on the pbx
• With build in sw-version, coming with pbx-software
• With latest sw-package, uploaded with auto-provisioning-modules
• Package and module can be downloaded via the wiki-pages (http://wiki.gigaset.com)
• Automatically via WebUI of the phone
• Via Gigaset.net server (if profile.gigaset.net/device is entered in server-field)
• Via Gigaset pro PBX (if ip-address is entered in server-field)
• Manually via WebUI of the phone
• Download firmware from product-pages (http://gigaset.com/pro) and upload it manually via WebUI

The latest versions of the PC-software (integrations installer and GS Quicksync) can be downloaded via the Gigaset pro product pages (http://gigaset.com/pro).

Recommendations

Depending on the environment the equipment is installed, following recommendations are given. Medium to high traffic/load (also just peaks) in the network would probably recommend following settings:

Switch
• VLAN for separating phone- and computer-network
• TOS/Diffserv for Quality of Service (QoS) in LAN
• Enable Port-switching (Multi-IP/-MAC) when using buildin switches of telephones (DE310/410/700/900IP PRO,
DX800A and N720IP))

Router
• Router should have enough CPU power to avoid bottlenecks in transmission
• Use VLAN to divide the networks for computer (best effort) and telephony
• Enable QoS in the network (LAN and WAN (upload, if available))
• Don’t use SIP ALG (if available)
• Use business router instead of consumer hardware
• Use HW VPN if interconnection between multiple sites is used
• Use Wi-Fi with minimum of 702.11g (n is preferred)

Cabling
• 100/1000MBit switches for internal traffic
• Cat 6 (or 7) cabling to ensure Gigabit-compatibility
• Using WLAN-clients only in exceptional case (DE900IP PRO)
• Don’t use powerline communication
• Minimize the number of cascade-switches (star-topology preferred)

ISP
• Use business ISPs which can guarantee stability of the line
• Check bandwidth for up- and download when using VoIP-provider
• Codec G.711 uses ca. 100kbps per call (good voice-quality)
• Codec G.729 uses ca. 45kbps per call (average voicequality, no fax-transmission)

Provider connection

General
• Check requirements for external, parallel calls in the company (normally ca. 10 % of total users)
• Check internal call-rates
• Use only trusted provider (preferred the certified provider)

PSTN
• Use only for fallback
• Use Digium TDM404EF (Gigaset-edition) 4-port FXO PCI-card
• Use Digium TDM422EF (Gigaset-edition) 2-port FXS & 2-port FXO PCI-card
• Use Digium TDM440EF (Gigaset-edition) 4-port FXS PCI-card

ISDN/S0
• Use Digium B410PF (Gigaset-edition) 4-port SO PCI-card
• Check supported features of your line
• Check echo-cancellation settings of your line (card supports hw-ec)
• Use crossed cables only for internal S0-bus
• Use normal ISDN-cable (or lan-cable) for external S0-bus

E1/PRI
• Use Digium TE122BF (1-port) or TE207PF (2-port) (Gigaset-edition) PCI-card
• Check supported features of your line
• Check echo-cancellation settings of your line (card supports hw-ec)
• Check jumper position for internal or external bus of the port
• Check maximum possible parallel calls of the line

VoIP
• Use only certified provider (see WebUI of T300/500 or wiki)
• Check maximum possible parallel calls of the line
• Check used codec when using fax-functionality (e.g. G.729 doesn’t support fax-transmission)
