Decimal Name Description Reference
1 sip.audio This feature tag indicates that the device supports audio as a streaming media type. [RFC3840]
This feature tag indicates that the device supports application as a streaming media type. This feature tag
2 sip.application exists primarily for completeness. Since so many MIME types are underneath application, indicating the ability [RFC3840]
to support applications provides little useful information.
3 sip.data This feature tag indicates that the device supports data as a streaming media type. [RFC3840]
4 sip.control This feature tag indicates that the device supports control as a streaming media type. [RFC3840]
5 sip.video This feature tag indicates that the device supports video as a streaming media type. [RFC3840]
6 sip.text This feature tag indicates that the device supports text as a streaming media type. [RFC3840]
7 sip.automata The sip.automata feature tag is a boolean value that indicates whether the UA represents an automata (such as [RFC3840]
a voicemail server, conference server, IVR, or recording device) or a human.
8 sip.class This feature tag indicates the setting, business or personal, in which a communications device is used. [RFC3840]
The sip.duplex media feature tag indicates whether a communications device can simultaneously send and receive
9 sip.duplex media ("full"), alternate between sending and receiving ("half"), can only receive ("receive-only") or only [RFC3840]
send ("send-only").
The sip.mobility feature tag indicates whether the device is fixed (meaning that it is associated with a fixed
10 sip.mobility point of contact with the network), or mobile (meaning that it is not associated with a fixed point of [RFC3840]
contact). Note that cordless phones are fixed, not mobile, based on this definition.
11 sip.description The sip.description feature tag provides a textual description of the device. [RFC3840]
12 sip.events Each feature tag value indicates a SIP event package supported by a SIP UA. The values for this tag equal the [RFC3840]
event package names that are registered by each event package.
The sip.priority feature tag indicates the call priorities the device is willing to handle. A value of X means
13 sip.priority that the device is willing to take requests with priority X and higher. This does not imply that a phone has [RFC3840]
to reject calls of lower priority. As always, the decision on handling of such calls is a matter of local
policy.
Each value of the sip.methods (note the plurality) feature tag indicates a SIP method supported by this UA. In
14 sip.methods this case, "supported" means that the UA can receive requests with this method. In that sense, it has the same [RFC3840]
connotation as the Allow header field.
Each value of the sip.extensions feature tag is a SIP extension (each of which is defined by an option-tag
15 sip.extensions registered with IANA) that is understood by the UA. Understood, in this context, means that the option tag [RFC3840]
would be included in a Supported header field in a request.
Each value of the sip.schemes (note the plurality) media feature tag indicates a URI scheme that is supported
16 sip.schemes by a UA. Supported implies, for example, that the UA would know how to handle a URI of that scheme in the [RFC3840]
Contact header field of a redirect response.
17 sip.actor This feature tag indicates the type of entity that is available at this URI. [RFC3840]
18 sip.isfocus This feature tag indicates that the UA is a conference server, also known as a focus, and will mix together [RFC3840]
the media for all calls to the same URI.
19 sip.byeless The feature tag is a boolean flag. When set it indicates that the device is incapable of terminating a session [RFC4235]
autonomously.
This feature tag contains one of three tokens indicating if the device is rendering any media from the current
20 sip.rendering session ("yes"), none of the media from the current session ("no"), or if this status is not known to the [RFC4235]
device ("unknown").
21 sip.message This feature tag indicates that the device supports message as a streaming media type. [RFC4569]
22 sip.ice This feature tag indicates that the device supports Interactive Connectivity Establishment (ICE). [RFC5768]
This feature tag contains a string containing a URN that indicates a unique identifier associated with the UA
instance registering the Contact. Values appropriate for use with this feature tag: String (equality
23 sip.instance relationship). The feature tag is intended primarily for use in the following applications, protocols, [RFC5626]
services, or negotiation mechanisms: This feature tag is most useful in a communications application, for
describing the capabilities of a device, such as a phone or PDA.
24 sip.app-subtype This feature tag indicates the MIME application sub-types supported by the agent for purposes of streaming [RFC5688]
media.
25 sip.fax This feature tag indicates whether a communications device supports the ITU-T T.38 fax protocol ("t38") or the [RFC6913]
passthrough method of fax transmission using the ITU-T G.711 audio codec ("passthrough").
26 sip.uui-isdn This media feature tag when used in a Contact header field of a SIP request or a SIP response indicates that [RFC7434]
the entity sending the SIP message supports the package "uui-isdn".
27 sip.src This feature tag indicates that the UA is a Session Recording Client for the purpose of an RS. [RFC7866]
28 sip.srs This feature tag indicates that the UA is a Session Recording Server for the purpose of an RS. [RFC7866]
This media feature tag, when inserted in the Contact header field of a SIP REGISTER request, conveys that the
29 sip.pnsreg SIP UA associated with the tag is able to send binding-refresh REGISTER requests associated with the [RFC8599]
registration without being awakened by push notifications.
This feature tag indicates that the device supports CLUE-controlled media. Values appropriate for use with
this feature tag: Boolean. The feature tag is intended primarily for use in the following applications,
30 sip.clue protocols, services, or negotiation mechanisms: This feature tag is most useful in a communications [RFC8848]
application for describing the capabilities of a device to use the CLUE control protocol to negotiate the use
of multiple media streams.

Presently we were in a very dark road, and at a point where it dropped suddenly between steep sides we halted in black shadow. A gleam of pale sand, a whisper of deep flowing waters, and a farther glimmer of more sands beyond them challenged our advance. We had come to a "grapevine ferry." The scow was on the other side, the water too shoal for the horses to swim, and the bottom, most likely, quicksand. Out of the blackness of the opposite shore came a soft, high-pitched, quavering, long-drawn, smothered moan of woe, the call of that snivelling little sinner the screech-owl. Ferry murmured to me to answer it and I sent the same faint horror-stricken tremolo back. Again it came to us, from not farther than one might toss his cap, and I followed Ferry down to the water's edge. The grapevine guy swayed at our side, we heard the scow slide from the sands, and in a few moments, moved by two videttes, it touched our shore. Soon we were across, the two videttes riding with us, and beyond a sharp rise, in an old opening made by the swoop of a hurricane, we entered the silent unlighted bivouac of Ferry's scouts. Ferry got down and sat on the earth talking with Quinn, while the sergeants quietly roused the sleepers to horse. Plotinus is driven by this perplexity to reconsider the whole theory of Matter.477 He takes Aristotle¡¯s doctrine as the groundwork of his investigation. According to this, all existence is divided into Matter and Form. What we know of things¡ªin other words, the sum of their differential characteristics¡ªis their Form. Take away this, and the unknowable residuum is their Matter. Again, Matter is the vague indeterminate something out of which particular Forms are developed. The two are related as Possibility to Actuality, as the more generic to the more specific substance through every grade of classification and composition. Thus there are two Matters, the one sensible and the other intelligible. The former constitutes the common substratum of bodies, the other the common element of ideas.478 The general distinction between Matter and Form was originally suggested to Aristotle by Plato¡¯s remarks on the same subject; but he differs325 from his master in two important particulars. Plato, in his Timaeus, seems to identify Matter with space.479 So far, it is a much more positive conception than the ?λη of the Metaphysics. On the other hand, he constantly opposes it to reality as something non-existent; and he at least implies that it is opposed to absolute good as a principle of absolute evil.480 Thus while the Aristotelian world is formed by the development of Power into Actuality, the Platonic world is composed by the union of Being and not-Being, of the Same and the Different, of the One and the Many, of the Limit and the Unlimited, of Good and Evil, in varying proportions with each other. The Lawton woman had heard of an officer's family at Grant, which was in need of a cook, and had gone there. [See larger version] On the 8th of July an extraordinary Privy Council was summoned. All the members, of whatever party, were desired to attend, and many were the speculations as to the object of their meeting. The general notion was that it involved the continuing or the ending of the war. It turned out to be for the announcement of the king's intended marriage. The lady selected was Charlotte, the second sister of the Duke of Mecklenburg-Strelitz. Apart from the narrowness of her education, the young princess had a considerable amount of amiability, good sense, and domestic taste. These she shared with her intended husband, and whilst they made the royal couple always retiring, at the same time they caused them to give, during their lives, a moral air to their court. On the 8th of September Charlotte arrived at St. James's, and that afternoon the marriage took place, the ceremony being performed by the Archbishop of Canterbury. On the 22nd the coronation took place with the greatest splendour. Mother and girls were inconsolable, for each had something that they were sure "Si would like," and would "do him good," but they knew Josiah Klegg, Sr., well enough to understand what was the condition when he had once made up his mind. CHAPTER V. THE YOUNG RECRUITS Si proceeded to deftly construct a litter out of the two guns, with some sticks that he cut with a knife, and bound with pawpaw strips. His voice had sunk very low, almost to sweetness. A soft flurry of pink went over her face, and her eyelids drooped. Then suddenly she braced herself, pulled herself taut, grew combative again, though her voice shook. HoME²Ô¾®Ïè̫ʲôÐÇ×ù
