Dear All ,

I have a strange problem with VRS in TOPAZ system concerning there is no DTMF once the call enter the VRS and the caller try to dial the extension there is no DTMF and there is a silence

I made the loop test between extension and trunk port and ringing to this ext the VRS answer and i can dial any internal extension , that is mean there is a problem between PSTN provider and topaz system concerning on DTMF there is no synchronize

I have tried call with provider to help me but there is no results , Is there any command on topaz to adjustment the DTMF on the system or can any body guide me to solve this problem ?
