Configuring a Streaming Audio Server
If the Linksys ATA boots and finds that the SAS line is on-hook, it will not remove battery from the line
so that IVR may be used. But if the Linksys ATA boots up and finds that the SAS line is off-hook, it will
remove battery from the line because no audio session is in progress.
Example SAS with MOH

Configuring the Streaming Audio Server
The following provides step-by-step procedures for implementing an SAS with an external music
source.
Step 1
Connect an RJ-11 adapter between the music source and an FXS port on the
Linksys ATA
(Phone 1 or
Phone 2).
Step 2
On the administration web server, click the SIP tab and scroll down to the Streaming Audio Server
section (see
Figure 1-16
).

Step 3
On the SAS Enable pull-down selection list, select
yes
.
Step 4
In the MOH Server field of the Call Feature Settings section, enter the User ID configured for the line
attached to the audio source.
If the line is not registered with the SIP proxy, enter the IP address and SIP port number configured for
the line.
Step 5

Using a FAX Machine with the SPA2102 or SPA8000
Note
T.38 Fax is only supported on the SPA2102 and the SPA8000. The SPA2102 supports a single
connection, whilethe SPA8000 supports one connection for each pair of ports (1/2, 3/4, 5/6, and 7/8) for
a maximum of four connections.
Procedure
To optimize fax completion rates, complete the following steps:

Linksys ATA
Administrator Guide
Document Version 3.1
Chapter 3
Configuring Linksys ATAs
Using a FAX Machine with the SPA2102 or SPA8000
Step 1
Upgrade the ATA firmware to the latest version
Step 2
Ensure that you have enough bandwidth for uplink and downlink.
For G.711 fallback, it is recommend to have ~100Kbps.
For T.38, allocate at least 50 kbps.
Step 3
To optimize G.711 fallback fax completion rates, use the following settings on the Line tab of the
Linksys ATA:
Network Jitter Buffer: very high
Jitter buffer adjustment: disable
Call Waiting: no
3 Way Calling: no
Echo Canceller: no
Silence suppression: no
Preferred Codec: G.711
Use pref. codec only: yes
Step 4
If you are using a Cisco media gateway for PSTN termination, disable T.38 (fax relay) and enable fax
using modem passthrough.
For example:
modem passthrough nse payload-type 110 codec g711ulaw
fax rate disable
fax protocol pass-through g711ulaw
Step 5
Enable T.38 fax on the SPA 2102 by configuring the following parameter on the Line tab for the FXS
port to which the FAX machine is connected:
FAX_Passthru_Method: ReINVITE
Note
If a T.38 call cannot be set-up, then the call should automatically revert to G.711 fallback.
Step 6
If you are using a Cisco media gateway use the following settings:
Make sure the Cisco gateway is correctly configured for T.38 with the SPA dial peer. For example:
fax protocol T38
fax rate voice
fax-relay ecm disable
fax nsf 000000
no vad
Troubleshooting
If have problems sending or receiving faxes, complete the following steps:
Step 1
Send a test Fax in a controlled environment between two Linksys ATAs.
Step 2
Determine the success rate.
Step 3
Monitor the network and record the following statistics:

from the administration web server page.
Step 5
Enable and capture the debug log. For instructions, refer to Item

in
“Troubleshooting and

at the end of this chapter.
Step 6
Identify the type of Fax machine connected to the ATA.
Step 7
Contact technical support.
If you are an end user of Linksys VoIP products, contact the reseller or Internet telephony service
provider (ITSP) that supplied the equipment.
If you are an authorized Linksys Voice System partner, contact Linksys technical support.
Managing Caller ID Service
The choice of caller ID (CID) method affects the following features:
On Hook Caller ID Associated with Ringing – This type of Caller ID is used for incoming calls when
the attached phone is on hook. See figure below (a) – (c). All CID methods can be applied for this
type of CID.
On Hook Caller ID Not Associated with Ringing – This feature is used for send VMWI signal to the
phone to turn the message waiting light on and off (see Figure 1 (d) and (e)). This is available only
for FSK-based CID methods: (Bellcore, ETSI FSK, and ETSI FSK With PR).
Off Hook Caller ID – This is used to delivery caller-id on incoming calls when the attached phone
is off hook (see
Figure 1-17
). This can be call waiting caller ID (CIDCW) or to notify the user that
the far end party identity has changed or updated (such as due to a call transfer). This is available
only for FSK-based CID methods: (Bellcore, ETSI FSK, and ETSI FSK With PR).
