Hello,

i declare my interfaces like that in configuration

listen=udp:SIP_EXTERNAL_IP:5060 name "external" listen=udp:SIP_INTERNAL_IP:5060 name "internal"

how do i get the inferface name where the request was received ? 

i saw some pseudo variables that deals with received interface but it is always about ip or port or proto but not the interface name ( external or internal like mentioned in the configuration file ).

Thanks
