13.3.6 Limitations with SIP Outside Lines
The following calling features are not available when using SIP trunks or SIP Gateways:
• Consultation and call transfer (using *# or *7) by recipients of
Follow-Me-Anywhere call routes.
• Disconnection (hang up) of calls (using *#) when accessing outside lines
through the Message Center.

13.4 Digital Lines
Allworx refers to the integrated T1 interfaces on Allworx 24x and 48x servers as Digital
Lines. The Allworx 24x and 48x servers have two T1 Digital Line interfaces that are
accessed through the connectors labeled T1-A and T1-B. There are differences in T1
port functionality between the 24x and 48x servers.
13.4.1 Allworx 24x
The T1-A interface can operate as a Primary Rate ISDN line and/or as a T1 data line for
connectivity to another site or to an Internet Service Provider. That is, the T1-A interface
supports both circuit switched voice calls and TCP/IP data. The T1-A interface also
supports Robbed Bit Signaling (RBS) operation. The dedicated T1-B interface is for use
as a data connection.
Use the data connection for connectivity to another remote site on a dedicated T1 line or
for connectivity to a service provider for Internet access.
13.4.2 Allworx 48x
One or both of the T1 interfaces can operate as Primary Rate ISDN lines, Robbed Bit
Signaling (RBS) lines and/or as T1 data lines for connectivity to another site or to an
Internet Service Provider. That is, the interfaces support both circuit switched voice calls
and TCP/IP data.
Use the data connection for connectivity to another remote site on a dedicated T1 line or
for connectivity to a service provider for Internet access.
