This call routing table is only valid for PBX systems that forward the
special character star '*' for internal calls on their external bus. If the
PBX processes this character in a different manner, then the table
must be adapted accordingly.
3.2.3
VoIP telephony with extension numbers (SIP trunking)
This example explains the configuration of a SwyxConnect if an
existing ISDN PBX is to be extended with VoIP functions and where
the SIP line is to function as the main external "telephone line". The
SIP account is to work with a central switchboard number and
multiple extension numbers. All of the ISDN interfaces on the Swyx
VoIP Router will be connected to the ISDN PBX so that the
maximum possible number of lines is available for parallel calls.
The PBX is configured to allow subscribers to receive immediate
access to an outside line when they pick up the receiver.
The following functions are available to you after configuring the
Swyx VoIP Router:
• Internal telephony with ISDN and SIP telephones and SIP
softphones.
• Simultaneous external telephone calls from ISDN and SIP
equipment over the SIP account with multiple lines via the SIP
account.
