Is it also possible to t_relay the call a second time? For example relaying failed as the destination SIP proxy is not available can I redirect the call to an announcement server? e.g.:
if (!t_relay()){ if (t_lookup_request()) $du = "sip:announcement01@1.2.3.4"; t_relay(); exit; else sl_reply_error(); }
Yes, but only if you use append_branch() before t_relay(). t_relay() uses the request uri only when it is called for the first time. Subsequent invocation look to see if more branches are appended (if not they report an error).
