Bug Fixes
==================================
-- since 2.0.10(e)
 1. When both sides sending AVT tone at the same time, SPA may stuck at
    playing the DTMF tone until the call is ended.

 2. SPA does not accept any further reINVITE after rejecting last reINVITE
    with a non-2xx response in a dialog

 3. Removed static noise associated with G726r24 an G726r40 encoder

Feature Enhancement
===================================
-- since 2.0.10(e) --
 1. If <NSE Process NSE> is set to "no", the NSE payload type will
    not be included in outbound SDP

 2. Added <DTMF Process AVT> option in [Line 1/2]. If set to "no",
    AVT payload type will not be included in outbound SDP

 3. When sending CAS signal to the phone during CWCID (call-waiting caller-id)
    generation, do not mix in the normal voice audio

 4. Extended the parameter <RTP Packet Size> under [SIP tab] to
    allow specifying a different size for Line 1 an Line 2.
    Syntax: <Line 1 Packet Size>[,]
    If <Line 2 Packet Size> is not given, it will assume the same
    value of <Line 1 Packet Size>. Unit in seconds. Examples:
      .03,.1 ;30 ms for Line 1 and 100 ms for Line 2
      .06    ;60 ms for both Line 1 and Line 2

    Default is 0.030 (30 ms both Line 1 and Line 2; same as before)
    Notes: 
    - If parameter is blank, default value is used
    - If planning to use G723, minimum size is 30ms
    - All size values are limited to between 10 and 160ms
    - All values are rounded to the nearest 10 ms     

 5. Added UID1 and UID2 as valid provisioning macro variables, which
    expand to the contents of User_ID[0] and User_ID[1], respectively.

 6. Added <DTMF Process INFO> option under Line 1/2, to enable/disable
    playing back of DTMF tone on SIP INFO Messages. Default is "yes".

 7. Relaxed DTMF detection further when waiting for CAS ACK digit from
    the FXS port
