I’m running asterisk 1.4.1 with a couple snom320 phones and 3 PSTN lines (Zap/1-3). I can connect calls the phones just fine, but when I try to transfer using # or *2, nothing happens. The other end can hear the DTMF tones just fine, but asterisk doesn’t show any response in the CLI.
My SIP phones are set with canreinvite=no, which I had read fixed the problem for others. Any suggestions??
