[Freeswitch-users] DTMF missing digits

Wouldn’t it be better to allow the two FreeSWITCH boxes to talk directly to each other for calls between them? Eliminate the middle man and perhaps this and other problems disappear?

Subject: [Freeswitch-users] DTMF missing digits

 

I am experiencing problems with sonus dtmf. I tried setting different parameters related to the RTP BUGS listed in switch_types.h but it did not seem to fix the problem.

 

I have freeswitch ----> [carrier(sonus), ...]  -----> freeswitch

 

freeswitch sends the following digits to our carrier, and is received by the other end (also a freeswitch) missing the digits marked in black.

pcap shows the missing digits as being part of the previous packet, so two 1's becomes one 1 with the duration sum of two.

 

 1   -    1   -    2   -    1   -    1   -    #

 

What are the relevant parameters I should set?
