Re: Qsig Version question

Under the callmanager service parameters, you can select different QSIG protocols. Service->Service Parameters->Cisco CallManager->Advanced->QSIG Variant you can select ISO or ECMA. Also, you can change the ASN.1 Rose OID Encoding as well. As for the difference between ECMA and ECMA2, I believe the difference is how the channels are counted (which channels are d-channels and which are b-channels).
