In sr core, sip_resolvehost is pointing to dns_sip_resolvehost: resolve.h:#define sip_resolvehost dns_sip_resolvehost but in k core, sip_resolvehost is a standalone method. This is creating issues due to different signatures for the two methods: k core: struct hostent* sip_resolvehost(str* name, unsigned short* port, unsigned short *proto, int is_sips, struct dns_node **dn); sr core: struct hostent* dns_sip_resolvehost(str* name, unsigned short* port, char* proto); Modules affected by this: - enum - nat_traversal - nathelper Regards, Ovidiu Sas
