DAHDI: How To Supress Notification Of Changing CallerID On Transfer?

Hello out there,

I’m running an Asterisk 1.8.15-cert1 with DAHDI. Today I noticed that Asterisk is signalling to the calling party the current internal CallerID whenever I put a call to another internal phone.

Example:

Customer calls 020212345-555
-> IVR answers and puts caller to the chosen queue
-> Someone picks up the phone (Internal ext. 321)
-> CallerID shown on customers device changes to
020212345-321

Same when I park the call and pick it up on another phone.

I don’t want this to happen and can’t figure out how to disable this on DAHDI or at least the current channel. I tried “facilityenable=no” in chan_dahdi.conf, but this only supresses signalling the on hold status.

We are using a german ISDN “Anlagenanschluss” (bri_cpe) whith DDI served by the Deutsche Telekom, connected to a ISDN card which is used with DAHDI.

Is there a hidden config flag or something to disable this for DAHDI?
Or maybe a channel variable to temporarily disabling this on some channels?

THANK YOU!
