I have a M8L with firmw 5.3.12.
My sip account is registerd and outgoing calls are working. I have inbound call issues! After about 45min-1hour the inbound calls fail but outgoing calls are fine. i have made several changes in the generalconfig.cgi page but the problem persists! Currently i have to logg on the the epygi and deregister and register the sip account every 30 min to ensure the client can receive calls...(client is a lawyer...need i say more!!)
the settings are:
Sip subscripsion timeout: 3600 sec
Sip registration timeout: 3600 sec
Sip session refresh timeout: 3600 sec
PLease help!!!
