Hi, Im trying to send a custom header in a SIP Registration, but I can't find a way to do so. It looks like you should be able to call pjsip_regc_get_module() to get the sip registration module, but this gives me a linker error. Looking in footprint.c this method appears to be commented out. Should this be working or is there an alternative solution? Regards Spencer -------------- next part -------------- An HTML attachment was scrubbed...
