Hi all i have a asterisk server 16.11.1 (server A) that gets a call (leg A) and then calls a second server (leg B) server B is a freeswitch server

the servers are configured all thru with rfc2833 for dtmf the caller enters a number a long 15 digit number like a credit card number or even a phone number and in alot of cases server B always doesn’t get part of the digits from server A

running a trace on server (A) i checked the trace of leg A and of leg B on the same server (A) and i see that the from the provider to asterisk has all digits correct but leg b going out the same server has a missed digit

so either asterisk isnt getting all digits from the provider for some reason or it fails to regenerate the dtmf when sending to server b another think i noticed is asterisk generating a rtp (cn) packet to leg every time it misses

any idea how i can check what asterisk is seeing if its just sending the rtp without transcoding ?
does anyone have a idea of what might be the problem

using chan_sip rfc2833compensate=yes relaxdtmf=yes

thanks
