I am not able to receive DTMF tone on my VXML application when i have connected my CISCO 2851 with the SIP TRUNK from Telco .
I have done the CCSIP trace for your reference . Please suggest how can i rectify this error .
I dont have a TAC support . Please suggest how can I buy one. My Cisco components are pretty old one so probably not aware about the TAC .
If you can suggest how can i purchase one .
I am new to cisco so please guide me.
You can contact Cisco TAC directly their should be able to help you to get a TAC support contract
