■
To enable the use of multiple devices on a single Internet connection, the IP
addresses used in a LAN (often 192.168.x.x) are translated to a valid IP address
using address translation (NAT - Network Address Translation), but no status
information is available for NAT on an incoming RTP connection.To avoid this
problem, the IP address of a workplace computer or telephone visible on the
Internet is determined using a STUN server (STUN: Simple Traversal of UDP over
NAT). You can ask your SIP provider for the STUN server.’s IP address and port
number If you don’t need a STUN server, leave the
SIP Provider
field empty.
■
For direct SIP telephony using OpenCom 100, only SIP IDs consisting of
numbers for identifying subscribers registered with the SIP provider specified
can be addressed
■
For each SIP account you can create just one bundle. You can specify this
bundle in routes as a connection option. You can use a network provider rule
to specify the routing of numbers within a specific range to use SIP telephony
as a preference (see also
PBX Networking
, under
Configuration
starting on
page 133).
You can configure SIP connections in the
Configurator
on the pages
PBX Configuration
:

the technical attributes of a specific SIP provider, such as the IP addresses for the
registrar and the STUN server under
Provider
. Under
Accounts
enter the infor-
mation for an existing SIP account, such as the user name, password, assigned call
number and the maximum number of simultaneous calls possible.
