I am using some regular sip-phones and the internal sip-functions for HOLD and TRANSFER.
 
I do NOT use the applications “transfer/att_xfer” and “soft_hold”. The phone is a “Siemens OpenStage 60 G”, but this fact should not be important.
 
My problem is now that I can’t have different music for transfer and hold. If I would use the freeswitch-applications “transfer/att_xfer” and “soft_hold” then I would be able to set the variables “hold_music” and “temp_hold_music”.
 
Any idea to achieve this?
