[Sipping] Re: [Sipforum-discussion] SIP Telephony Device Requirements, Configuration and Data

Henry,

It is mentioned in the introduction to the document that "text shall be kept
in mind".

I suggest some specific text items to be entered that are in line with
existing standardisation, and accessibility needs and useful for all:

----------------------------------------------------------------------------
-------------------
SIP-xx, analogue text support: SIP adapter devices (for analog phone lines)
  MUST support conversion between real time text transmission using RFC 2793
[y]
  and text telephones according to ITU-T V.18 [x] allowing alternating use
of
  text and voice. SIP clients MUST fallback to G.711 if RFC2793 connection
fails.

SIP-zz, digital text support: SIP telephone devices MUST support
  real time text conversation using RFC 2793 [y] for the text stream.
  It MUST be possible to use text simultaneously with voice.

---------------------------------------------
In 4.11 Ringer Behaviour  : add the section below for the purpose of deaf,
hearing impaired, deaf-blind people and people in the garden and noisy
locations:

SIP Telephony devices MUST provide an external interface to
an external alerting system.

2000.
