Hi, > 1. Here is the message that i generate , is that correct message?
It seems that you are trying to use the CISCO format but it looks like you have put your Signal and Duration fields into the SIP message header instead of the SIP message body. See this... http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t11/ftinfo.htm The format is something like this: INFO sip:[EMAIL PROTECTED] SIP/2.0 Via: SIP/2.0/UDP 172.80.2.100:5060 From: <sip:[EMAIL PROTECTED]>;tag=43 To: <sip:[EMAIL PROTECTED]>;tag=9753.0207 Call-ID: [EMAIL PROTECTED] CSeq: 25634 INFO Supported: 100rel Supported: timer Content-Length: 26 Content-Type: application/dtmf-relay Signal= 1 Duration= 160 > 2. The CSeq start from 2, should it start from 1 ? It depends what the CSeq was for the previos request sent. If the previous request (I'm guessing this was an INVITE) had a CSeq of 1, then your INFO should use a CSeq of 2. Remember, you should increment your CSeq for every new request you send (not including retries). > 3. The server receive first dtmf tone without error , but it > show "unable to retrieve dtmf from INFO message" from second DTMF and above..
