If the caller is behind a private PABX (call center) you may need to use the command below to allow the caller to open a B Channel. When a call is from behind a PABX the exact number(extension) may be unknown and the telephone exchange identifies the source as "insecure". Using the "<UNSURE>" command allows the MultiCom to answer such a call.
| Code: | ISDN NumberEnabled <UNSURE>phonenumber <------for example
ISDN NumberEnabled 41216542000
ISDN NumberEnabled <UNSURE>41216542000 |
Simply add a second line for the phone number in question using the <UNSURE> command.
If no calls are getting through your MultiCom router or your ISDN line may be misconfigured. Try checking the following questions.
- You must have the Caller ID feature for you ISDN line. Be sure that your Telco has enabled this feature.
- Do you need a Multiple Subscriber Number (MSN) configured for each ISDN device on your phone line? Check with your Telco.
- Check that the PPP authentication information is correct (the type of authentication and the username and password.)
