Call forward on fxs

[jaume.dominngo]

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

Can you add

voice-port 0/1/1

timeouts interdigit 5

Yes, client only have two fxo lines. Inbound calls from analog pstn line are forwarded to analog gsm gateway conected to fxo port.

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

What is the delay like when you dial direct to the target number

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

Thanks for your support.
