Incoming call behaviour

Firstly, apologies for the rather vague subject title.

Here is the problem that I need to solve:

I am in the UK

When I have an incoming call from my PSTN (using a TDM400P), the caller hears three rings and then a ‘click’ that might be mistaken for a dropped call or someone bugging the line like it is demonstrated in films. Then there is a 5 to 10 second pause, as though asterisk is thinking. This is then followed by an internal ring out to several extensions in a ring group (US tones here, versus UK ringing tones on the initial ring).

The US rings are need to be changed, but this is not as critical as the wait - callers will thing the line is dead and break the call at the pause.

There is nothing obvious in the asterisk logs.

Please can someone give me a head start in dealing with this problem?



Try disabling the callerid setting in zapata.conf

I was experiencing something of the same think… I think asterisk is waiting for the callerid to come across the line.


Thanks for the help Brad.

I will try that and let you know


With the ringtone thing, you could try setting


in features.conf. I don’t know if this will affect the ring you’re talking about, but it’s worth a try - if you haven’t already.
