Subscriber Information
Parameter Name
Description
Type
Default
Display Name
Subscriber’s display name to appear in caller-id
Str23
User ID
Subscriber’s user-id. Usually a E.164 number
Str47
Password
Subscriber’s a/c password
Str23
Auth ID
Subscriber’s authentication ID
Str39
Use Auth ID
If set to “yes”, the pair <Auth ID> and <Password> are
used for SIP authentication. Else the pair <User ID> and
<Password> are used.
Bool No
Mini Certificate
Base64 encoded of Mini-Certificate concatenated with
the 1024-bit public key of the CA signing the MC of all
subscribers in the group.
Str508 Empty
SRTP Private Key
Base64 encoded of the 512-bit private key per subscriber
for establishment of a secure call.
Str88 Empty
Notes:
1. If proxy responded to REGISTER with a smaller Expires value, the SPA will renew registration based
on this smaller value instead of the configured value. If registration failed with an “Expires too brief” error
response, the SPA will retry with the value given in the Min-Expires header in the error response.
2. MOH Notes:
• The remote party must indicate that it can receive audio while holding MOH to work. That is the SIP 2xx
response from the remote party in reply to the re-INVITE from the SPA to put the call on hold must have
the SDP indicate a sendrecv or recvonly attribute and the remote destination address and port must not
be 0
Audio Settings
Parameter Name
Description
Type
Default
Preferred Codec
Select a preferred codec for all calls. However, the actual
codec used in a call still depends on the outcome of the
codec negotiation protocol.G711u, G711a, G726-16, G726-
24, G726-32, G726-40, G729a, G723
Choice G711u
Use Pref Codec Only
Only use the preferred codec for all calls. The call will fail if
the far end does not support this codec.
Bool No
Silence Supp Enable
Enable silence suppression so that silent audio frames are
not transmitted
Bool No
G729a Enable
1
Enable the use of G729a codec at 8 kbps.
Bool
Yes
G723 Enable
1
Enable the use of G723 codec at 6.3 kbps
Bool
Yes
G726-16 Enable
1
Enable the use of G726 codec at 16 kbps
Bool
Yes
G726-24 Enable
1
Enable the use of G726 codec at 24 kbps
Bool
Yes
G726-32 Enable
1
Enable the use of G726 codec at 32 kbps
Bool
Yes
G726-40 Enable
1
Enable the use of G726 codec at 40 kbps
Bool
Yes
DTMF Tx Method
Method to transmit DTMF signals to the far end: Inband =
Send DTMF using the audio path; INFO = Use the SIP
INFO method, AVT = Send DTMF as AVT events; Auto =
Use Inband or AVT or INFO based on outcome of codec
negotiation
{InBand,
AVT,
INFO
Auto}
Auto
DTMF Process AVT
If set to yes, SPA will include AVT payload type in its SDP
and will process AVT (DTMF) packets sent by the peer.
Else, it will not include AVT payload type in the SDP.
Bool Yes
Release Unused Codec
If set to yes, SPA will relinquish all the low bit rate codecs
included in the original SDP that are not supported by the
called party; hence other concurrent calls can reuse these
Bool Yes
