I was traveling and no much time to follow up on mailing list ...
Did you use set_contact_alias() before handling the subscribe with presence module? You should not change the contact in the way you do, some UA may reject it when receiving requests.

Ok. solved
I moved record_route for subscribe to other part of the config file and for now if msg_apply_changes() works so if someone intrested in solution:
For me it works like this
if(is_method("SUBSCRIBE")) { if ( $pr == "wss" ) { xlog("L_INFO", "$rm from WSS proto. contact : $ct "); remove_hf("Contact"); append_hf("Contact:sip:$fU@$si:$sp;transport=ws\r\n"); msg_apply_changes(); xlog("L_INFO", "New contact : $ct "); $fs = "tls:"+INTERNALIP+":7443"; }
handle_subscribe(); t_release(); This code saves valid contact at the active_watchers table for this SUBSCRIBE request and generates NOTIFY via correct transport.

So the only way i found to say where to send notify is to change $ct variable with adding postfix ";transport=ws" Because based on it module wil build NOTIFY but here are 2 troubles 1) $ct variable is readonly (remove and append contact header has no any effect for this. msg_apply_changes says: "cannot apply msg changes after adding record-route header - it breaks conditional 2nd header") 2) as i said i can not change anything at the tm:local-request for notify as i wrote at the prevoius messages here. IT changes needed variables but it has no effect on message So main question - how to save real transport at the contct field at the active_watchers table.

Back to the reported topic, can you paste here the db record from active_watchers table? Then, you should be able to update some parts of the local generated requests by having an event_route[tm:local-request] block in your kamailio.cfg.
