@arkadiam Pretty sure we are both trying to do same thing judging by your dispatcher and routing config, multi domain telephony integration with a cloud comms platform?
Its frustrating that SNI is being flakey as it works very nicely if you have a single cert with multiple SAN's defined but that less than ideal from a management point of view (but doesnt seem to have the performance hit loading multiple certs has #2312 )
For sake of completeness my virtually identical config is as follows: ```event_route[tm:local-request] { if(is_method("OPTIONS") && $ru =~ "vendor.com") { xlogl("L INFO", "Dispatcher Pinging ruri: $ru turi: $tu furi: $fu"); append_hf("Contact: sip:$fd:5061;transport=tls\r\n"); tls_set_connect_server_id($fd); xlogl("L INFO","SNI ID: $fd"); } } ```
