Questions and answers
Net traffic in idle state
Why are the values from my PC provided by “Ping” so poor?
If the device is in idle state, the network capacity is reduced as far as possible. If in this state, “Ping”
packages (ICMP Echo Requests) are sent to the Aastra Phone 312 from the outside, the answers
often take more than one hundred milliseconds. The device will automatically adjust the network
activity depending on the state. If, for example, the “Ping” tool is used from the telephone, it aborts
the WLAN idle state. Then, Pings from the outside will be answered immediately.
Operation behind a firewall or a DSL router
Why do I have problems behind my DSL router?
The Aastra Phone 312 has been designed for the use in local company networks. Currently, no
mechanisms for bypassing NAT routers and firewalls are installed (e.g. STUN). The functionality
behind such devices can thus not be guaranteed.
What is the difference between user name, user ID and authentication name?
The user name in the telephone options is used as display name for SIP. This is the one that is shown
as name at the party receiving the call (if applicable).
The user ID from the SIP profile often corresponds to the telephone number. In a SIP URI, this is the
part in front of the ‘@’. If no separate authentication name is set-up, the user ID is still used for the
authentication if the server requests this.
It is possible to set an authentication name (auth. name) if it is different from the user ID. There are,
for example, installations, in which the user ID corresponds to the telephone number, while the
authentication name is an abbreviation of the real name, e.g. "JPublic".
