Hi All, I am seeing the following issue with SUBSCRIBE for simple-message-summary while interoping with a Metaswitch proxy. (DC-SIP/2.0).
send SUBSCRIBE, Expires: 3600 recv 200 OK, Expires: 3600 recv NOTIFY, Subscription-State: active send 200 OK recv NOTIFY, Subscription-State: active send 200 OK recv NOTIFY, Subscription-State: active send 200 OK recv NOTIFY, Subscription-State: active send 200 OK recv NOTIFY, Subscription-State: terminated;reason=timeout send 200 OK The last NOTIFY comes at about 3600 seconds after the SUBSCRIBE. It appears that each NOTIFY is restarting the re-SUBSCRIBE timer. I get the following debug messages: nta: NOTIFY (547975483) going to existing leg nua: nua_stack_process_request: entering nua(0x10a236e8): nua_notify_server_preprocess: active () nta: sent 200 OK for NOTIFY (547975483) nta: timer set to 32000 ms nua(0x10a236e8): event i_notify 200 OK nua(): refresh subscribe after 1432 seconds (in [900..2700]) Until the last NOTIFY where I get the following messages: nta: NOTIFY (547975485) going to existing leg nua: nua_stack_process_request: entering nua(0x10a236e8): nua_notify_server_preprocess: terminated (timeout) nta: sent 200 OK for NOTIFY (547975485) nta: timer set to 32000 ms nua(0x10a236e8): event i_notify 200 OK nua(0x10a236e8): removing subscribe usage with event message-summary So I have a couple of questions. Should sofia-sip be restarting the subscription timer on each NOTIFY ? If so, then it appears the proxy is in error by timing out. Does that make sense ? Shouldn't I get an event when the subscription usage is removed ? Is there some indication that the subscription usage has been removed in the NOTIFY event ? I'm still running 1.12.6. Has any of the SUBSCRIBE/NOTIFY logic changed since ?
