ZEPHYR XPORT USER’S GUIDE

I can dial local calls just fine, as can the far end. Why can’t I place a long distance call?

There may be a problem with your long distance carrier. Try dialing a test call with a different carrier. In the USA & Canada, you can force a call to a specific carrier by using a 101xxxx access code. If this solves the problem, be sure to follow up by contacting your carrier, or setting up and account with another carrier. The following access codes are just a few of the available carriers (Note: for ISDN “Zephyr mode” calls use one of the first 3 listed).

1010222

(MCI)

1010321

(Telecom USA)

1010288

(AT&T)

1010345

(Lucky Dog)

1010333

(Sprint)

1010220

(Telecom USA)

hHOT TIP! While these access codes are handy for troubleshooting, in many cases the rates using them can be very high. We strongly recommend directly contacting a long distance company and establishing an account.

I am unable to establish calls using POTS from the Xport to the Zephyr Xstream at the station.

Check the following:

Is the Xstream at the station properly configured and working?

Can it dial from B channel one to B channel 2 as described in the Xstream manual? If not, what happens? See the Xstream manual for more assistance on troubleshooting ISDN.

Can it accept calls from a Telephone? If not, what happens? In rare cases, an ISDN line might not have the ability to accept “Circuit Switched Voice calls” enabled. In that case you will need to have your Telco enable “circuit switched voice” for at least one B channel.

Can the Xport place a call to a Telephone?

If you call a telephone using the “Call Type” of XPORT, the far end should hear a modem tone after it answers.

If you call a Telephone using the “Call Type” of PHONE, the far end should hear your audio, and you should be able to hear them speaking on the Xport.

You may need to enter a “9”, “8”, or other number before you dial. If so, you may need to enter a pause between this digit and the rest of the number (or you may sometimes get the wrong number). Listen carefully to the Received headphones while dialing to hear what is happening. In this case use the <#> or <*> key to enter the <,> character (pause) when dialing.

Can the Xstream and Xport in question call the Telos Test line?

I can’t place a call using ISDN in Zephyr mode.

Can you place a call using ISDN using the “Phone” mode?

If so, then your ISDN line may not be configured to allow Circuit Switched Data(CSD) calls. If you cannot place calls using either call mode, then see the next question.
