[Freeswitch-users] DTMF relay over bridge and the delay

Hello, Caller A calls in through a SIP trunk and is bridge to Destination B on another SIP Trunk. When A dials a DTMF digits, there is a delay of ~1.5 seconds before it's played on Leg B. When B Leg dials a DTMF digit, there is only a short delay of ~0.3 before it's relayed on Leg A. Is there anyway to reduce this delay or remove it? It causes problem with Auto Attendant menus on Leg B. Any help is very much appreciated. Thanks, Ali Pey
