No special config is needed, as it works same as a phone.

You don't need station-id commands when caller id is working.

Hello Paolo

Thanks for your reply.

My fax machine number will be 12346375.

Can you explain me how the incoming/outgoing fax will be delvered to FXS card on number 6375. I have a 4 port FXO card on my router.

voice-port 1/1/3

description ***>FAX

station-id name SiteXXX_FAX

station-id number 6375

Configure a dial-peer for the FXS port, and connection plar to that destinaion under the dedicated FXO port.

Hi Clark,

Can you share your running-configuration with us.

dial-peer voice xxx pots

destination-pattern [2-9].......

port 0/0/2

!

I assume the xxx dial peer is for out going (the FXO port)

dial-peer voice yyy pots

destination-pattern 6375

port 0/1/0

!

the yyy dial-peer for FAX device.

!

create translation rules for incoming and outgoing like (called number) /^12346375/ /6375/ and (calling number) /^6375/

/12346375/ and apply in under dial-peer xxx and yyy

Try this working or not.

Regards

Selvarathnam

There is no need for translation rules with the OP scenario.

Dear Paolo and Nadar

Thanks for the reply,

I have some questions for my understanding please reply.

• I Have 2 lines with number given by ITSP 12345677,12345678 i connected those to FXO card and from those FXO port i configured  connection plar so the incoming call is routing directly to the FXS  port where the FAX is connected, instead of 1 to 1 mapping suppose if i have 20 users then what will be configuraton.
  
• As mentioned above i have 2 lines 12345677,12345678 I have used 12345678 for fax but sometimes the Fax receive by the receipeint seen the number as 12345677 and sometimes 12345678, i want the fax number to be seen by other corporates as 12345678 only.
  

Thanks

FXO cannot receive the called number (no DID support), for that you need a digital circuit, or SIP.

In other words with an analog line you cannot do better than 1:1 for mapping to fax.

Dear Paolo,

I am very new to CVOICE, so please bare with me to make me understand.i have some general questons below not related to fax.

I have read before in Cvoice book that there is no support for DID on FXO port but say

• for ex: i have  20 users working in a coporate and corporate has 2 lines,then there must be a operator in the corporate to transfer the calls for the desired extension of the caller. is it my thoughts are correct???
• so if i have 2 lines for my corporate then the internal users will be seen to PSTN users by any of the 2 no's lines         (12345677,12345678) but not always by the same line. is it my thoughts are correct???

Please correct me if i 'm wrong.

[paolo bevilacqua]

1. Operator or AutoAttendant.

2. For lines in hunt-group, telco can make so that for outgoing calls, caller-ID is always the pilot number.
