Call forward on fxs

Hi I have a client with a UC540, who wants to divert incoming calls to an external number. The problem is that when the client makes this divert the caller hears a tone, ten seconds of silence and more tones (the external number does not start ringing until these last ten seconds.). The lines are fxs. How i  could reduce that time?

Hi,

This sounds like you are using the default inter digit timer of 10 secs

Try adjusting this

on cli config

!

telephony-service

timeout interdigit 4

The problem persists. Could it be that the UC, look for line in all FXO ports?

Yes is delayed, I will try to  change the gsm gateway, because it seems to hang randomly.

Thanks for your support.
