Changing CPC on Asterisk TDM400P

Hello,

I would like to change the CPC (Calling Party Clear) signalling settings for my TDM400P.

I’m using BT and they use a different “Disconnect Clear Time” (their word for CPC) depending on the line. This affects whether Asterisk sees the user as hung up.

I know I can turn CPC on and off, but where do I set the timing for this?

are you loading the wctdm driver with the right settings ? have everything configured for UK ?

I only have one module on the card (FXO) that connects to my phone line.

modprobe wctdm opermode=UK
