Chapter 1: Introduction

EN
If SIP or ISDN users at the LANCOM VoIP Router are entered into the SIP
PBX with different passwords, then the users have to enter their individual
passwords upon registration. Consequently, each SIP or ISDN user has an
entry into the LANCOM with the individual passwords, which are also
entered into the SIP terminal devices. Users with shared and individual
passwords can be managed in parallel.
Particular aspects for ISDN users
Integrating ISDN terminal equipment into the LANCOM VoIP environment and
the necessary steps for configuration depend upon the application at hand
and, if applicable, upon the options available with a PBX. The main questions
to be answered by the user are as follows:
Can ISDN terminal devices telephone internally with SIP users?
Are ISDN terminal devices available externally over SIP lines?
Can ISDN terminal devices telephone externally over SIP lines?
