telephone speaker will disrupt calls at other telephones using
VoIP trunks in the vicinity of the fax machine. Here are some
suggestions to minimize the possibility of your VoIP calls being
dropped because of fax tone interference:
Locate fax machine away from other telephones.
Turn the speaker volume on the fax machine to the lowest level,
or off, if that option is available.

not enabled on the trunk.
