[asterisk-users] Aastra phones occasionally show "No Service" - Is there any network setting I can tamper to facilitate a quick DHCP renewal on the Aastra phones?

[bruce bruce]

Hi Mike,

I am putting the phones on AC Adapter now as I am suspecting the Linksys POE
switch. Once that test is done and if problem still presists, I will be
enabling DHCPMasq and also set the SIP registration time to 1 second on the
phone UI.
