Hello There

I haver run into a issue. After running ser for 1 hour all the phones cannot call reach other and ip phones are not reachable from pstn gateway any more. I assume this is due to the registration expiration. Is there any way to reinforce (force Reregister call ) from ser to the UA so they do not become unavailable. I understand that i can increase the expiration time from 60 to 45 days but i don't think it is good idea. Thanks. Appreciate any help. Decebal
