Bug Fixes
==================================
-- since 3.1.3 --

.
    <Conference Bridge Ports> value is swapped between Line 1
    and Line 2
.
    CIDCW Ack digit (A or D) is sent OOB if DTMF Tx Method is INFO.
    The symptom is that the other party may hear the ACK
    digit if the peer device will play OOB DTMF via SIP INFO msg

.
    <Detect ABCD> setting has no effect if DTMF Tx Method
    is INFO; ABCD is always sent OOB regardless the setting.

====================================    
Feature Enhancement
====================================
-- since 3.1.3 --

.    Allow macro expansion of $A to $D in User-Agent field configuration.  These
     macros correspond to provisionable parameters GPP_A to GPP_D.

.    Support bell 202 and also v.23 FSK standard for caller-id generation.
     Select by setting <Caller ID FSK Standard> to "bell 202" or "v.23"

.    Distinguish between FAX Passthrough mode and Modem Passthrough Mode.
     Modem Passthrough Mode can only be triggered by predialing the
     <Modem Line Toggle Code>. FAX Passthrough Mode is triggered by
     CED/CNG tone or NSE events. Echo canceller is automatically disabled
     for Modem Passthrough Mode only. Echo canceller is automatically disabled
     only if <FAX Disable ECAN> (Line 1/2) is set to "yes" for that line
     (in that case FAX passthrough is the same as Modem passthrough).
     Call-waiting and silence suppression is automatically disabled for
     both FAX and Modem passthrough as before. In addition, out-of-band 
     DTMF Tx is disabled during modem or fax passthrough 

.    Added <Jitter Buffer Adjustment> Line 1/2 paramters to control how
     jitter buffer should be adjusted. Choices are:
     up and down: jitter buffer size can go up or down
     up only: jitter buffer size can only go up (up to the max value of 950ms)
     down only: jitter buffer size can only go down (up to the min value of 30ms)
     disable: jitter buffer size is fixed

.    Added "extremely high" additional optin to <Network Jitter Level> parameter.
     The initial jitter buffer size for each level are:
     low: 30ms
     medium: 40ms
     high: 60ms
     very high: 100ms
     extremely high: 160ms

.    Added <SIP Reg User Agent Name> which, if specfied, is the user-agent name to be
     used in a REGISTER request. If not specified, the value in
     <SIP User Agent Name> will be used for REGISTER request also.
     Default value is blank.

.    If Line 1 and 2 uses the same <SIP Port> value and 
     option is enabled, then the <Proxy> IP address for both Line 1 and 2
     are treated as acceptable IP address for both Lines since the unit
     cannot distinguish for which Line a inbound message is for unambiguously

.    Added <Emergency Number> which is a comman separated list of 
     emergency number patterns. If outbound call matches one of the
     pattern, SPA will start emergency call handling:
     - Disable Hook Flash event handling
     The condition is restored to normal after the phone is on-hook.
     Default value is blank (no emergency number); max length is 63 chars.
    
.    All phone number template accepts %xx escape in the pattern
     where the character represented by %xx is matched against literally.
     For example, to include a * in a pattern, use %2a, such as
     %2a123 matches "*123" (note that * in the pattern is wild card that
     matches any number of charaters).
     This applies to the parameters: <Ring1 Caller> - ,
     <Cfwd Sel1 Caller> - , 

.    After a REGISTER request fails for whatever reasons, 
     the next REGISTER retry will not include preemptive credentials
     until challenged by the registrar again. This prevents a viscious
     cycle with some proxy server that will keep sending 403 (instead
     of 401 or 407) when REGISTER comes with invalid preemtive
     credentials.

.    Increased allowed length of 
     <SIP User-Agent Name> and  parameters to 127 chars.
