[OpenSER-Users] lack of notify, subscribe problem

Hey I've got 2 issues with pub/sub: 1. Openser does correct subscription on grandstream 2020 phone. But then anything happens: register, invite, whatever from monitored phone, openser doesn't generate any notifications for subscribers. Any pointers on it? Is there some variable, that I should set to enable those? 2. Phone issue. Trying to start subscribe on snom 190 - messages sent are: ----- SUBSCRIBE ... ... Event: dialog Accept: application/dialog-info+xml ----- 202 OK ----- NOTIFY ... Event: dialog;sla Subscription-State: active;expires=3600\r\n ----- 489 Bad Event ----- Anything I can do about it? I've tried it with svn version with the same effect. Couldn't really find anything in docs that I could change in config. pub/sub is handled with simple handle_publish/handle_subscribe - nothing fancy in config - just location storing on register and message passing. Thanks for all info.
