Incoming Call Ring Delay

Hi,
I have installed an Asterisk system in Cyprus with a Digium TDM400P 4 FXO Card (TDM04B).

When an Incoming call comes in it takes a while until the phone start ringing. Is not like an analogue phone where when an incoming call comes in it starts ringing immediately. I realised that when I have in the line both an IP PBX phone and an analogue phone (that is connected directly to the Service Provider Plug) , the analogue rings 2 times and then the IP PBX phone starts ringing. Do i need to do any configurations to fix that ? This is a big issue for me since some of my callers hung up the phone before i pick it up.

I tried /etc/asterisk/zapata.conf setting “immediate=yes”. but it did not work

I have two in a live environment now. They both have the same two ring delay. I’m not sure if their is a solution, but I dont see why it takes 2 rings before the card detects anything. If someone has a solution please list it.

Thanks

I have the same problem on my zap card too. Two rings before if detects a call.

disable callerid in zapata.conf.
