2.2 Programming12 Programming GuideHTTP SettingsQSIG Connectionless Tunneling SettingsOthersDetailed ExplanationsDHCP ServerWhen using the DHCP feature, the IP address settings of the card (IP address, subnet mask, anddefault gateway) will be assigned by a DHCP server.However, keep in mind that the maintenance of the card is performed through a web browser from aPC; hence you must know the IP address of the card. Therefore, it is necessary to set up the DHCPParameter & Description Default Value Range# HTTP Port No.Specifies the port number for HTTP communications by thecard.Generally, there is no need to change the default value.80 1 to 65535Parameter & Description Default Value Range# QSIG Connectionless Tunneling Port No.Specifies the port number for connectionless tunnellingbetween cards at different locations in a QSIG network.Generally, there is no need to change the default value.Notes• Connectionless tunnelling enables the PBXs on aQSIG network to use enhanced networkingfeatures. (For more information about thesefeatures, refer to the relevant sections of the HybridIP-PBX documentation.)• If you are using a gatekeeper, and "Routed" isspecified for the parameter Call Signaling Model(see "2.2.2 H.323 Parameters"), connectionlesstunnelling is not possible. In this case, the PBXcannot use the enhanced networking features.1718 1 to 65535Parameter & Description Default Value Range# LAN Disconnect Threshold Time (s)Specifies the time (in seconds) until disconnection from theLAN is recognised.For example, even if a LAN cable is disconnected during acall, reconnecting the cable within this time period maintainsthe call.5 1 to 10
