I'm trying to authenticate a statement by a voip/sip system integrator that dhcp has stability and reliability issues because when the phone rings (every time, according to this company) it has to check its lease for renewal and potentially renew the lease before the call can connect. _______________________________________________ In the very strictest sense, a device must check whether its DHCP lease has expired before sending or listening for a packet using that IP address. But of course, this "checking" is done negatively -- the stack knows what address to use, and the higher-layer DHCP daemon removes the address from the stack at those rare times when the daemon cannot renew the lease. DHCP does *not* have stability and reliability issues in an environment that implements DHCP well -- that has coordinated, redundant DHCP servers, which almost every IP network does. DHCP is used in this manner by many, many enterprises, many of which have hundreds or thousands of IP phones. There may be certain specialized environments where using DHCP for VoIP phones is not a good idea, but you need to have someone explain exactly why.
