Recording inbound call including DTMF - possible ?
Hi I need to measure DTM digits duration and interdigit delay for various phones in a two stage dialing scenario. I.e Phone dials DID and after answer then the second number My set-up is: Phone->PSTN network->DID(inband DTMF) ->FS I ha ve FS to answer the call and record the call - all this is fine. However when i analyse the rdecording the Digits are being cut off down to 10 msec "bursts" - I trust its FS that cust the DTMF in order to avoid further propogation inband to second leg of the call. Is theer a way to avoid this ? I.e record the inbound call without DTMF processing ? Thx Morten

Nope if its rfc2833 its not us cutting the dtmf if you have a TDM gateway in the mix that is prob. what is doing it.

No. The blib of DTMF you hear is not ours to remove its the remote gateways job... FreeSWTICH usually only does 2833 so it could be hearing the little bit of DTMF coming in or out from the endpoints. If you check the cdr hangup you'll have digit_log which will be a log of all digits dialed during the call.

Are you using freeswitch to detect the inband dtmf or are you getting both inband and some other method (rfc 2833?) of dtmf as well? Mike On Sep 13, 2009, at 10:27 AM, Morten Henckel wrote:
