no, i have not configured hardware confrencing.. but it should work because i am using G711 codec and 4-FXO lines are used for connection from PSTN. when two parties are outside and one party is inside (ip phone) the call is disconnected.. i think it should work....any suggestion..

Hello Nareh,
I hope you are doing great,
I would like to confirm with you if there is by any change possible if you can provide us a complete call flow, at this momment I think this will be the call flow.
PSTN---(FXO)VG--CUCM----IP_Phone
Can you provide us this information:
show run of the voice gateway.
configuration of the voicegateway with the call manager. ( Screenshot will be better ).
traces of the call manager. Making a conference with the two pstn phones.
Do you have any security device on the middle: ASA, PIX, Firewall.
I hope you can provide me this information in order to see the problem, and try to provide you a resolution.
Regards,
Luis
