can you confirm if the engine has “sendrpid” and “trustrpid” set to yes in the SIP configuration?
No I can’t for the moment. You cannot reproduce in demo?
Alexandre cannot reproduce when setting “sendrpid” and “trustrpid” set to yes
It is not reproductible either on demo and wazoglobal
Please don’t use chan_sip parameters. I don’t understand this ticket, this is only parameters we haven’t set by default. Probably we could discuss to enable it by default, but this is not a bug … With the good parameters you have also the good caller ID on interception and attended transfer.
