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

.  <Conference Bridge Ports> value is swapped between Line 1
   and Line 2 internally

.  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"

.  Echo canceller is not automatically disabled when FAX tone is detected unless
   < FAX Disable ECAN> (new Line 1/2 parameter) is set to "yes"

.  Added < Jitter Buffer Adjustment> Line 1/2 paramters to control how
   jitter buffer should be adjusted. 

.  Added "extremely high" additional optin to < Network Jitter Level> parameter.

.  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

.  Added < Emergency Number> which is a comma separated list of 
   emergency number patterns. If outbound call matches one of the
   pattern, SPA will disable Hook Flash event handling.
   Maximum length of this field is 63 chars.
    
.  All phone number template accepts %xx escape in the pattern
   where the character represented by %xx is matched against literally.
   This applies to the parameters: < Ring1 Caller> - < Ring8 Caller>,
   < Cfwd Sel1 Caller> - < Cfwd Sel8 Caller>, < Emergency Number>

.  After a REGISTER request has failed, the next REGISTER will not 
   include preemptive credentials
