• user-name is the name of the subscriber, such as “Joe Smith”. Maximum length is 32 characters
• user-id is the User ID of the subscriber, which must match exactly the user-id used in the INVITE
when making the call, such as “14083331234”. The maximum length is 16 characters.
• expire-date is the expiration date of the MC, such as “00:00:00 1/1/34” (34=2034). Internally the
date is encoded as a fixed 12B string: 000000010134
The tool generates the <Mini Certificate> and <SRTP Private Key> parameters that can be provisioned
to the Linksys ATA.
For Example:
gen_mc ca_key “Joe Smith” 14085551234 “00:00:00 1/1/34”
Produces the following Mini Certificate and SRTP Private Key:
<Mini Certificate>

Configuring a Streaming Audio Server
This section describes how to use and configure a streaming audio server (SAS). It includes the
following topics:
• Music On Hold, page 3-12
• Using a Streaming Audio Server, page 3-13
• Using the IVR with an SAS Line, page 3-13
• Example SAS with MOH, page 3-14
• SAS Line Not Registered with the Proxy Server, page 3-14
Music On Hold
On a connected call, the Linksys ATA may place the remote party on hold by performing a hook-flash
to initiate a three-way call or by swapping two calls during call-waiting. If the remote client indicates
that it can still receive audio while the call is holding, the Linksys ATA can be configured to contact an
auto-answering streaming audio server (SAS) to stream audio to the holding party. When used this way,
the SAS is referred to as an MOH Server.
