We have an ELX3000 with sagnoma 12 port card. I am having an issue with DTMF's repeating when you call IVR's. I have tried adding the relaxdtmf=yes but to no avail. I have also made sure the Aastra 57i's are not forcing rfc2833 out of band. The lines that are coming in are broken out of an IP T1. I have tried setting the dtmfmode to auto and to inband with no luck. Any Ideas???
