[asterisk-users] How to ignore REFER entirely with chan_sip or PJSIP ?

[Olivier]

Hello,

In my testing, I saw that Asterisk always included a REFER value in each
INVITE's Allow header, no matter how allowtransfer/allow_tranfer was set.

Is there a way to remove this REFER value entirely either globally or
specifically for a given peer/endpoint ?

Which telephony feature would loose without REFER method ?


Best regards
