Configuration Notes: This section contains a detailed description of how the Allworx 6x was configured for
interoperability testing with Integra Telecom services.
Network Requirements: As in any VoIP deployment there must be adequate bandwidth to support VoIP
traffic. A proper network assessement should be performed before any VoIP deployment.
Assumptions:
All SIP Signalling uses UDP on port 5060.
SIP Signalling packets use Differentiated Services Code Point (DSCP) 24.
Real-Time Transport Protocol (RTP) uses DSCP 46.
Licenses: The Allworx Ip PBX must be equipped with licensing to support SIP Trunks.
