Why I cannot make two VoIP calls at the same time? When try to make a 2nd call the display always shows "not possible".
If you wish to permit two VoIP connections, do the following steps:
- Open the Web Configurator
- Open the menu "Settings" - "Telephony" - "Audio"
- Activate the option "No" next to "Allow 1 VoIP call only"
Please Note: If, however, your DSL connection has a narrow bandwidth, there may be problems if two VoIP calls are made at the same time.The data is no longer transferred properly(long voice delay, datalosses etc.).
