[hung.le]

Hi everyone,
I am facing with a problem with OXE.
i have an oxe with IP trunking. If i make a call from a IPTouch or Digital phone via IP trunk to a remote IVR system, when i dial suffix (*) to active DTMF, the call drop immediatly. But if i active DTMF from softkey, it has no problem
It's is only happen on IP trunk for recent 2 days, Before it worked normal

anyone have experience with this prolem, pls share with me.

Hi,

try..!!

TrunkGroups/auto.DTMF dialing on outhoing call : Yes

BOL

[vad]

suffix * or prefix?
If you dial IVR_number+* and wait for IVR answer. In this case *=suffix.
If you dial IVR_number, wait for IVR answer and dial *. In this case * must be prefix (External feature/ DTMF End-to-end dialing).
