In AOIP/SIP mode, the device uses the SIP
protocol to negotiate the coding algorithm and
establish the connection.
▪
The device can register with up to five SIP
accounts on up to five different SIP servers
When registered with a SIP server, a connection
▪
can be established by dialling a phone number.
By entering an IP address in the dialling window,
▪
the connection is established via Direct SIP with
no need for a SIP server.
It is recommended to use an AOIP provider, or a
▪
self operated SIP server. Telephony providers
usually don't support high quality audio codecs.
Using an account with telephony providers gives
▪
access to the public telephone network in SD-
and HD-Voice quality.
TABS 1-5: There is a tab for each SIP server. The
▪
account credentials must be entered on the AoIP
(LAN / SIP) configuration page.
