Guys, is there any way that I can set a registration of a set to not expire? I have a Mitel 5215 phone that looses its registration with the Asterisk server after a period of inactivity and I have to manually re-register the phone. There must be a workaround for this I hope!
Thanks,
Hi guys has anyone figured this out , I have having the same problem with Mitel 5212 phone with version 8 firmware .I tried to reduce the registration timeout from 360 to 120 but the problem still persits.the fact that every monday morning the phones act up is a sign of inactivity for sat and sun .In my case the phone will say registered but you cannot ping it or dial it . please 
Give it a fixed address, and don’t use registration.
