Choosing the Line to Use
There’s a configuration setting in the Telephony PBX drivers that asks if the
phone should poll for new lines when it is started up.This is a double-edged
sword. If it searches and finds nothing, the phone starts up using the last successful
settings. If it searches and finds new lines, you’ll be prompted to choose
which of the new lines to add to your phone.The issue here comes from having
a mal-configured CallManager, where a mobile user is attached to the network
via a slow dialup connection. If the connection is terribly slow, less than 14.4
Kbps, SoftPhone may slow while trying to establish (or re-establish) a connection
to CallManager. For the most part, mobile users will only use one line, so it’s recommend
that this setting be left unchecked and empty.
