Skype SIP Trunk Setup
1.00
Overview
The DSX is compatible with Skype Connect SIP Trunking. This setup guide summarizes the account
information you will receive from Skype and provides step-by-step instructions on how to program that
information into the DSX.
You can set up SIP trunks as standard loop start lines or DID lines. All the feature available with other
types of loop start and DID lines are also available with Skype Connect SIP trunk lines. For details on the
features available with loop start and DID lines, refer to the on-line DSX Software Manual at:
http://www.necdsx.com/docs/dita/dsx_v3_complete/index.html

Assign SIP Lines
1231-01: IP Lines [SYSTEM: PORTS: IP LINES: IP LINE ASSIGNMENT]
The first DSX SIP line is the first line beyond the last assigned line. Each SIP line uses an IP
resource (licensed VoIP port) in DSX. The maximum number of VoIP licenses is 8 in DSX-40 and
16 in DSX-80/160.
Example with DSX-40:
•
The first SIP line in a DSX-40 without a COIU expansion card is line 5. Available SIP line
numbers are 5-12.
•
With the COIU expansion card installed, the first SIP line is line 9. Available SIP line
numbers are 9-16.
•
DSX-40 supports a maximum of 8 VoIP licenses. When the total number of licenses are in
use, only Peer-to-Peer calls are available.
Example with DSX-80/160:
•
The first SIP line in a DSX-80/160 with a single 8COIU card is line 9. Available SIP lines
are 9-17.
•
The last line number in DSX-80/160 is 64. In a system with an 8COIU and two T1/PRI
cards, this will limit the available number of SIP lines.
•
DSX-80/160 supports a maximum of 16 VoIP licenses. When the total number of licenses
are in use, only Peer-to-Peer calls are available.
1232-01: IP Line Provider Number [SYSTEM: PORTS: IP LINES: IP LINE ASSIGNMENT]
Assign each SIP line in DSX to a provider number (1 or 2). DSX supports up to two providers
simultaneously.
Example: If Skype is your only SIP trunk provider, assign all the SIP lines designated in 1231-01 to
provider 1.
1232-02: IP Line Username [SYSTEM: PORTS: IP LINES: IP LINE ASSIGNMENT]
1232-03: IP Line Password [SYSTEM: PORTS: IP LINES: IP LINE ASSIGNMENT]
These options are not used with Skype Connect SIP trunks.
