Hello - I have CCM 4.2(3) and a 3845 MGCP gateway. Between the gateway and my legacy IVR (Edify Workforce) I have a T1-CAS circuit. I can successfully place a call into my IVR. My IVR has a script that allows me to input an extension and be transferred. When I punch in the extension on my IP phone, the IVR sends a hookflash to my 3845 gateway over the T1-CAS. When this happens I get disconnected. I tried to set up hookflash on CCM with T1-CAS but it seems that the only option for signalling is E&M. I'm curious why that is??? My IVR needs to do loop-start. I know this is the reason things aren't working right. Any suggestions on how to solve my hookflash problem would be appreciated.
Thanks,
Jason
