Sorry about the lack of info. It's a simple SIP only setup. A handful of sip phones, an asterisk server, and a sip provider. The DTMF signals from the sip phones are received by Asterisk because they can access features like *1. The DTMF signal from the called party are received by Asterisk because they can also access features like *1. But, the DTMF tones are not passed through from the Sip Phone to the Called Party. The same happens regardless of whether its an incoming or outgoing call. That means, if any of my users try to call a company with a menu system, they can't select any options. How can I tell if Asterisk is sending the tones through to the provider? I need to find out whether its something I'm doing, or something the provider is doing. Any ideas? Thanks Dan
