Page 74: Dns Name Resolution
Internet Access You can also use the Forum 525/526 as an Internet access server in a LAN with an IP-enabled server. To do this, you must enter the Forum 525/526 IP address on the server as the default gateway. In addition, you must edit the internal DNS server configuration so that the resolution of external DNS names is forwarded to the Forum 525/526.
Page 75: Ras Access
Forum 525/526 in a LAN with an IP-enabled Server There are two different ways of suitably configuring the internal DNS server. You can enter the Forum 525/526 IP address as a DNS forwarder. If you require access to extended DNS information, you can also configure the DNS server for a recursive DNS request without the DNS forwarder.
Page 76: Branch Link
Branch Link You can use the Forum 525/526 to interlink two LANs via ISDN. To do this, you configure two Forum 525/526 systems so that they can dial in to each other. In order for this to work, the two LANs must be configured for different IP address ranges (subnetworks).
Page 77: Useful Information On Internet Access
Useful Information on Internet Access In the Configurator, Network: Branch menu you can configure the dial-in settings. The Forum 525/526 will set up a connection whenever a IP data transfer to the other LAN is requested. Note that such a connection is only set up when specific requests are made.
Page 78: Using The Web
One of the most important services in the Internet is e-mail. E-mails are buffered in individual e-mail accounts on a mail server. Mail servers are operated by ISPs for example. With the Forum 525/526 you can set up one or more e-mail accounts for every user account configured on the Forum 525/ 526.
Page 79 The protocol will function without TCP/UDP port numbers, e.g. ICMP or IGMP. The Forum 525/526 NAT has suitable processes for ensuring the functions of many important protocols affected by these rules. These are the protocols FTP (in “active” mode), CuSeeMe (“videoconferencing”), IRC (“chat”), ICMP errors (“traceroute”) and ICMP echo (“ping”).
Page 80: Voice Over Ip (Voip)
Integrating the two communi- cation networks into a single communications network can provide consid- erable savings. The Forum 525/526 gives users all the features of system telephony through its use of an IP-based protocol. Furthermore, the standardised SIP protocol can also be used on the intranet.

Page 85: Fundamentals
Fundamentals you click on Reset licences, the available licences will be reassigned with the next incoming or outgoing calls. Fundamentals VoIP makes the transmission of voice and telephony signalling via IP (“Internet Protocol”) possible. After a connection is established, the terminal collects voice data (PCM data), which is then sent to the receiver using an IP packet.
Page 86: Voice Quality
Fundamentals The length of the voice-data packets must therefore be adjusted to the requirements of the transmission medium. Shorter voice-data packets can be sent if a direct ethernet connection exists. If an 64 kbit/s ISDN line is to be used for transmission, then longer voice-data packets should be used. Longer voice data packages are generally used for SIP telephony over the Internet.

Various IP-based protocols are used for system telephony via the Internet protocol (“IP”) (see also Start Procedure starting on page 110). Multiple TCP connections are made between an IP telephone and Forum 525/526 for the telephone’s start procedure, registration and signalling.
Page 90: Voip Profiles For Sip
After successfully agreeing on a codec, the resulting RTP connection is established between the terminals directly. The Forum 525/526 communications system can also serve as a proxy for the media data stream (“RTP Proxy function”) if external SIP lines do not allow direct RTP data connection between the terminals.
Page 91 The extended codec list contains definitions for codecs which are used by the usual SIP terminals. The codecs on this list are for usage in VoIP profiles and are not directly supported by the Forum 525/526 communications system.

Page 94: Sip Telephony
The SIP Internet (Session Initiation Protocol) protocol provides you with a low- cost, standardised option for telephoning via IP-based networks. The Forum 525/526 enables you to use external SIP telephone connections (“SIP trunk lines”). The Forum 525/526 communications system supports configuration of standard SIP lines with one call number for each as well as extension-capable SIP-DDI lines with base call number and extension.
Page 95: External Sip Connections
● You must log on (“Login”) to the SIP registrar before you can use SIP telephony. Use the Forum 525/526 to manage important information for the registration (user name and password) of one or more SIP accounts. It is possible to make several calls simultaneously using a single SIP account.
Page 96 For this reason, incoming RTP calls often fail to get past the Firewall or NAT configuration of the Internet gateway product used. If you do not use the Forum 525/ 526 as the Internet gateway, the product should be compatible with SIP telephony.
