Avaya 4621SW IP . Message lamp indicator problem

Hi ,

Im testing Asterisk with avaya phones, and I cant put the MWI working (" Got Sip Response 400 ‘Invalida Subscription-State’ back from ")…, besides that my phones seems to unregister after a couple of hours.
anyone experienced this problem with avaya phones?


Hi Cassador

How did you connect the phone?
I mean we have Avaya phones and I would like to connect them in a Asterisk base. What is the CLAN ip address for the Asterisk? What is the port (¿1719?)?
Works it fine?
