I have a cordless phone connected to PABX and PABX connected a voice gateway. As the cordless phone press the digits then press the 'Call' to send out number, one of the digit has been lost as below. The 8 of 8453 will be lost.
68453 ---> Call
6 access voice gateway
8453 region extension
Can anyone tell me what the problem is and how to fix it ?
