Dear friends, I would want to know how to configure ftmod_sangoma_isdn to send dialtone. My setup is as follows, Telcom <---> Freeswitch <---> PBX <----> Extensions 1..n My pbx has got overlap dial enabled and it is configured to seize the trunk when it receives '0' from extensions. When I connect the PRI to my pbx, and when '0' is dialled from an extension, my pbx seizes the trunk and I'm able to hear dialtone. But, when I connect the PRI to freeswitch and connect freeswitch to pbx and when '0' is dialled from an extension, I'm not hearing dialtone. Whether some configuration is available to ask ftmod_sangoma_isdn to send dialtone before started to collect digits in overlap mode? or any other way to give dialtone?? -- Regards, Nagalenoj H.
