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 phone to use port 5061 to
send SIP TLS 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 as referenced in RFC3891.
The phones support switching between early media and local
ring tone.
Allows you to enable or disable the microphone during early
media.
Allows Administrators to change the phone's codec
negotiation behavior so that the phone will indicate only one
preferred codec in the SDP when replying to an SDP offer (as
per 3GPP TS 24.229).
A "Call-Info" header is included in the 200ok response to an
INVITE, RE-INVITE, and UPDATE messages for SCA lines.
No configuration is required for this feature.
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.
