uc520 outbound call to auto-answering systems

We just installed a UC520 system to one of our clients and they have a problem when calling anybody that has an automated attendant. When the called party auto attendant asks you to enter a number to select an option, the option is not being selected. I advised client to try use # or * before the number but still won't work. Can you please advise? Client is using SIP trunk.

Hello Spitm012,

We have moved your question from the Collaborations Partner Community to this more technically focused Small Business Support Community as you will have a better chance of finding a technical resolution here.

Thank You,

There is information in this thread that may help you

basically you need to match the dtmf-relay configuration in your outbound dial-peers to what your SIP provider supports.
