Hello, I am sending DTMF events via SIP INFO to a Cisco AS5350 gateway and the returns with a "481 Invalid CSeq Number" (see below). The previous was an INVITE with cseq 1 which returns in an 200 OK.
What are we doing wrong here? is this some known issue with Cisco AS5350? any help would be much appreciated! regards, prasad.
