Incoming Calls
The following example shows the default behavior of your ZyXEL Device for
incoming calls when two SIP accounts are configured and you are using two
phones. When a call comes in from your SIP account 1, the phones connected to
both phone port 1 and phone port 2 ring. Similarly, when a call comes in from your
SIP account 2, the phones connected to both phone port 1 and phone port 2 ring.
In either case you are not sure which SIP account the call is coming from.

In the next example, phone port 1 is configured to use SIP account 1 and phone
port 2 is configured to use SIP account 2 for incoming calls. In this case, every
time you receive a call from your SIP account 1, the phone connected to phone
port 1 rings. Similarly, every time you receive a call from your SIP account 2,
phone port 2 rings. To apply these configuration changes you need to configure
the
Phone Device
screen. See
Section 16.6 on page 243
.

DESCRIPTION
RFC Support
PRACK (RFC
3262)
RFC 3262 defines a mechanism to provide reliable transmission of SIP
provisional response messages, which convey information on the
processing progress of the request. This uses the option tag 100rel and
the Provisional Response ACKnowledgement (PRACK) method.
Select
Supported
or
Required
to have the ZyXEL Device include a SIP
Require/Supported header field with the option tag 100rel in all INVITE
requests. When the ZyXEL Device receives a SIP response message
indicating that the phone it called is ringing, the ZyXEL Device sends a
PRACK message to have both sides confirm the message is received.
If you select
Supported
, the peer device supports the option tag
100rel to send provisional responses reliably.
If you select
Required
, the peer device requires the option tag 100rel
to send provisional responses reliably.
