We are an ISV company that integrates Asterisk telephone systems (Digium cards) with external systems and we have a big issue.
We 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 after the 2 rings the IP PBX phone starts ringing. Do i need to do any configurations to fix the issue with the delay ? This is a big issue for me since some of the customers hung up the phone before I the IPPBX pick it up.
All the clues are leading to the fact that there is something wrong with the configuration of the Digium Card.
I tried /etc/asterisk/zapata.conf setting “immediate=yes”. but it did not work
This is for zapata.conf
; Zapata telephony interface
; Configuration file
rxwink=300 ; Atlas seems to use long (250ms) winks
; Whether or not to do distinctive ring detection on FXO lines
;Include genzaptelconf configs
;Include AMP configs
