Not receiving all digits from FXS device

carllougher

Hi,

I've got a fax machine plugged into an FXS port on a 2800 router.

Inbound fax works fine but when dialling a destination number on an outbound fax call I only receive the first digit.

Qu:

Is the router processing the call before all digits are presented?

Is there a way of delaying the digit collection before sending to the router?

Outbound Call path:

Fax > FXS > router > Sip server > Isdn gateway

If I manually overide the digits with a destination number on a translation rule it works a treat.

Any clues?

Try changing "destination-pattern ." to the "destination-pattern .T" on your voip dial-peer.

I have previously tried that but still no go.

Do you think its anything to do with timeouts on the fxs port?

When using .T interdigit timeout should be 10 seconds by default and that seems long enough for any fax machine I've ever seen. I have a feeling that something else is wrong here - can you please get the "debug voice dialpeer all" for a call. I would like to check if we're hitting the right dial-peer.
