Firmware Release 1.2.1(2283) has been posted. One enhancement includes is the
addition of options to support NAT traversal for SIP Gateway and URL calls
on SP1/2: You can now append the following URL parameters to each speed dial and
SIP Gateway VG1-8 access number, separated by ';',
user-info, password is optional
- op=[ i ][ m ][ n ][ s ]
option flags, i=ice, m=symmetric-rtp,
SpeedDial = sp2(firstname.lastname@example.org;ui=1000:xyz;op=sm)
VG1-8 AccessNumber = SP1(sip.inum.net;user=1000;op=imns)
Note that if userid or password is specified in VG1-8 AccessNumber,
it overwrites the settings in AuthUserID, and AuthPassword in the VG.
If stun disabled in the main SP, then stun client is not enabled,
and may lead to crash when doing URL dialing and stun specified.
