Will asterisk 1.0.X wirk with CCM cisco call manager. CCM is version 6.1 They said they entered a SIP trunk for me. I have a sip.conf context of [CCMEAST] type=friend host=x.x.x.x disallow=all allow=ulaw allow=alaw context=CCMEAST When I call into the test number I get busy. This OLD machine is running a quad T1 card. I cannot update to 1.2 or 1.4. I tried once and it did not work I had to go back to 1.0. Customer is wanting to migrate to SIP and not use the T1 at all but got to have it working first. Thanks, Jerry
