How to generate local call tones

Unanswered Question
Feb 20th, 2008

Hi all,

I have a question relating generating a local call tone.

What we have in place and configured is the following:

Callmanager 4.2(3)SR3 and a MGCP controlled 2811 Gateway including two E1 interfaces connecting our company to the PSTN.

My issue now is this:

When colleagues of me try to call our colleagues in Bulgaria, the call actually traverses the gateway to our PSTN-provider, and then a certain and unknown amount of other telephony provider until it reaches the destination in Sofia.

In dependence of the second or third provider in this row (the call traverses) the caller gets no call tone. The display just indicates "calling". But often the caller doesn't look at his display and just expects the call tone.

(And go on-hook in case he get no calling tone...)

Is there a possibility to generate this calling tone locally (at the gateway or in callmanager) in case no tone has been sent by the provider?

Thanks in advance,


I have this problem too.
