SIP problem with Header Alert-Info
A problem found only on pfSense (of the 4 routers I tested): whenever I use a Page command (from Asterisk, locally outside the network) and send the Alert-Info header first (to tell me SIP phones to auto-pickup the call) the phone rings but don`t pick up the call, as if the Alert-Info header was mangled or absent.
Yes I am using sipproxy, don`t have a choice
With all other routers, the phones simply work as they should.
How can I start troubleshooting/giving more info about this to help?
pfSense itself wouldn't touch/mangle the SIP contents, that is likely being broken by siproxd, you'd have to start your troubleshooting there.
Thanks, will check with the siproxyd people.
