Hi everyone,
i just configured my srst to support sip phones. During fallback all phones (sccp and sip) are able to register to the srst router. First i try sip to sip are working, then sip to sccp are also working, but when i tried sccp to sip i get an error tone. Then all calls either sip or sccp started to fail. I observered that call failure starts when sccp calls to sip phones.
Try rebooting the sip phones and call was restored (sip to sip and sip to sccp). But again when sccp to sip the call fails and then every call fails again. Upon dialing it just dead air and after a couple of seconds there is an error tone. Try adding a dial-peer but it did not work
