Hey all, Just added a new feature to chan_dahdi called ss7_explicitacm. It was added in response to the previous thread about how someone wanted to be able to send a REL with a certain cause code before an ACM was sent on the link, which was impossible before because as soon as we started the call into the dialplan we sent ACM automatically. Now, if you set the ss7_explicitacm option to yes, in order to send ACM, you must use the Proceeding() application in your extensions.conf. Hope that helps some people. I wasn't able to test it before I committed it, but it was a very simple patch to add. Please let me know if you have any issues. Matthew Fredrickson
