I have a UC500 set up and don't really have many problems with it, but recently some users report that certain touch tone menus (eg when calling banks etc) don't work, they press the button nothing happens.
Is there anyway to configure the settings for this, so the options are recognised by all menus?
The menus work fine from none voip phones
Thanks for your help, I find this website very useful
This is not one of our certified CCA SIP Trunk providers, so I don't know what DTMF relay method they support. You will need to ask them that, and then configure (using CLI) the proper option under your SIP outbound dial peers (inbound if you have calls to AA coming from the SIP trunk):
UC500(config)#dial-peer voice 1002 voip
