Busy call, the user can hold, transfer, or disconnect the existing call.
On Voice First calls to a busy telephone that has an idle DN, the caller will get busy tone.
The caller can then dial the digit
SIP Trunk
Session Initiation Protocol (SIP) is an application layer protocol used for establishing sessions in
an IP network. SIP trunks allow the IPedge system to get PRI-like services from an Internet
Telephony Service Provider using SIP.
A SIP trunk allows an IPedge system to connect internal voice and private data traffic to the
outside public network (PSTN and public data) via IP.
When a user dials a call that will be sent over the PSTN, the call routing is sent over the WAN to
the Internet Telephony Service Provider (ITSP) that is providing the SIP trunk. This ITSP will
provide a connection to the PSTN through their equipment. The call will be sent from the IPedge
system to the SIP provider, who will act as a proxy, and send the call to the dialed destination.
For incoming calls, the SIP trunk acts somewhat like a DID trunk, the dialed number is sent to the
SIP provider and then routed over the IP Network to the IPedge system. This routing is based on
the URI and associated IP address.
Toshiba's SIP Trunk capabilities allow the IPedge system to communicate with a service provider
natively over an IP circuit, which can be used to carry voice and data simultaneously. Inside the
IPedge system, voice is converted to data and sent to the service provider along the same circuit as
the other data packets. This allows one circuit to be used for voice and data, it also allows data to
use all of the bandwidth when no voice is present. Quality of Service (QoS) is managed by the
service provider, allowing voice to instantaneously take priority over data.
SIP trunks offer ISDN-like features over a data connection (i.e. a T1 circuit). However, unlike a
traditional T1 circuit, a SIP trunk enabled circuit does not have to be physically provisioned and
divided to separate the voice channels from the data channels.

SIP Trunk Wizard

Toshiba has made programming SIP Trunks easier by giving the administrator the ability to enter
URI ranges. The URI field range allows the administrator to enter a range of the user portion of the
SIP Trunk URIs for the selected SIP Trunk service in the targeted server. The IPedge SIP Trunk
Wizard also allows for making URI ranges from DID numbers.The administrator can also define a
prefix which will be added to the front of each selected DID number to compose the URI. For
more details, refer to the SIP Trunk Feature Description.

Security

The IPedge system is built using Red Hat Linux® operating system. Linux has a secure file
structure making it less susceptible to viruses when compared to other popular operating systems.
Furthermore, there are fewer viruses targeting the Linux operating system.
