Support (FAQ)

Due to the increased volume of telephone traffic, the transfer points of VoIP providers may reach their capacity limits. A solution is sought by the providers through load balancing. The load distribution is done with a DNS SRV query. The DNS SRV is used to enable the provider to notify the registrars prioritised by him. The DNS resolution must be carried out by the provider. For this purpose, the router must use the DNS servers of the provider.

Current ICT systems:

• COMpact 4000
• COMpact 5000 (R)
• COMpact 5200 (R)
• COMpact 5500R
• COMmander 6000 (R) (RX)

Note the following points in the configuration:

• Under public networks, VoIP, provider, configure the appropriate provider. The default value 5060 must be set as registrar port and for the outbound proxy. The current templates are already preset for this.
• Under Administration, IP Configuration, the IP of the router or gateway must be entered in the 1st DNS Server field.

Early generations of hybrid telephone systems:

• COMpact 3000 analogue, ISDN and VoIP
• COMpact 5010/5020 VoIP
• COMmander Basic.2 / Basic.2 19“
• COMmander Business / Business 19“

These systems do not support the dynamic procedure and can therefore no longer be operated on the respective VoIP account after platform changeover. In these cases, the ICT system must be replaced by a compatible system.
