We are sending the correct digits - verified by a debug isdn q931 - but get the following error: "Cause i = 0x83E020 - Mandatory information element missing". Anyone seen this error or have an idea of what to look for. We have tried a couple different protocols
NI2 and 4ESS along with various parameters on the gateway with no sucess. Thanks!
