Description
Allows you to enable or disable the 802.1x Protocol support on the IP
Phones.
Allows you to enable or disable the phone to use port 5060 to send SIP
UDP messages.
Allows you to enable or disable the addition of the User-Agent and
Server SIP headers in the SIP stack.
The IP phones provide GRUU support using draft-ietf-sip-gruu-15. A
sip.instance is added to all non-GRUU contacts.
IP Phones support Sylantro Server features, like mandatory and
optional billing codes that require the application server to notify the
phone to collect more digits before completing the call. The IP phone is
able to collect digits in two stages to support the billing code feature.
Allows you to specify the Domain Name Service (DNS) query method to
use when the phone performs a DNS lookup.
Allows you to configure the phone to ignore CSeq number errors on all
SIP dialogs on the phone.
The phones support the "early-only" parameter in the "Replaces" header
according to RFC3891.
The phones support switching between early media and local ring tone.
Allows you to enable or disable the microphone during early media.
In Release 2.6 and up, a "Call-Info" header is included in the 200ok
response to an INVITE, RE-INVITE, and UPDATE messages for SCA
lines.
The IP Phones support the receiving of the Reason Header Field in a
SIP CANCEL message, as described in RFC3326.
On the IP Phones, an Administrator can enable or disable whether or
not the optional "Allow" and "Allow-Events" headers are included in the
NOTIFY message from the phone.
The IP Phones support a private extension to SIP for Asserted Identity
within trusted networks (as defined in RFC 3325).
The IP Phones support a parameter that enables or disables the
addition of the Route header in a SIP packet.
The phones provide a feature that allows an Administrator to shorten the
length of a SIP packet by using the compact form. This feature is in
accordance with Compact SIP Headers defined in RFC 3261.
The IP Phones support a parameter that allows you to enable or disable
the rejection of an INV or BYE with a "420 Bad Extension" if the INV or
BYE contains an unsupported value in the REQUIRE header.
The phones provide a feature that allow an XML Developer or
Administrator to define XML Key URIs that can send key press events to
the phone, just as if the physical hard key, softkey, or programmable key
were pressed on the phone.
