Dtmf between 2 asterisk servers pjsip

sending dtmf is working fine on endpoints registering to same server.

but whenever i try to transmit dtmf from an endpoint on my other asterisk server then it looks like it is not being transmitted or catched.

endpoint (dtmf) <–> asterisk1 <----> asterisk2 <---->endpoint(receive dtmf)
