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:

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:

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).
