We have a client running on a polycom vvx400 IP phone on our asterisk
The issue we have is the switchboard lady uses ## to transfer calls but sometimes it just does not work and just plays the DTMF tone to the calling party.
Is there any way to adjust the sensitivity of the blindxfer feature?
The polycom Transfer button is useless as there is a big delay until it apprears
I would greatly appreciate any advice
