I am about to setup a new Asterisk box which only uses SIP. I used to simply use menuselect with Zaptel and choose the tools that Asterisk required to exist and ztdummy. Now with Dahdi, I am reading http://svn.digium.com/view/dahdi/tools/tags/2.0.0-rc2/UPGRADE.txt?view=co and I understand I no longer can use menuselect as everything gets built. Everything looks pretty trivial except the echo canceller portion. I have never configured this on my SIP only systems without any physical hardware (no digium cards) so can what should be my strategy for running dahdi_cfg tool in this scenario where I have a few SIP did's coming in with several SIP phones on the inside? Thanks! jlc
