i have integrated a pbx with cisco 2811 router
the problem is when I dial from FXS router to PBX phone, the phone rings but when these phones wants to talk the connection will be broken
provide this command
The Sending Complete IE tells the switch that all the digits and information necessary for the call are contained in this Setup message.
Some switches in some countries want a Sending Complete information element to be included in the outgoing Setup message to indicate that the entire number is included. The Sending Complete IE is required in Hong Kong and Taiwan, and the isdn sending-complete command forces it to be sent.
please rate if helps
