[SIPForum-discussion] DTMF on SIP

[murali shankar]

Dear All,

            Please clarify me on the below quries
          1.How to find the DTMF option is accepting while making a call
through sip gateway ?
          2.Is there any relation between codec and DTMF signaling?
          3.Will the DTMF will get reverse? i.e if we enter the digit 1234
will it reply as 4321?


Thanks,
Murali
