Re: [Serusers] Global Failover Server

Hi DNS SRV is a Load Balance system, How it can be a fail over. Only for call initialisation a UAC will search for DNS SRV records, but after the the call starts, if First server (From which call is beaing initiated) goes down then thebye message will not go to second server net4.in Ritesh Jalan Senior Engineer - Business Solution Net4India Ltd.

Jacobsen Cc: seruser List Sent: Friday, July 07, 2006 2:00 PM Subject: Re: [Serusers] Global Failover Server Following lines are an extract from the SIPit preliminary report regarding supported DNS features in current implementations: Which gives a percentage of 38/73 supporting SRV records, so more or less half of the implementations supports this type of load balancing. This value should be used with care because implementations include both UAs and proxies/redirect/* servers. I can also say that a higher percentage of desktop SIP phones supports DNS SRVs, but since it's just my impression from the ones I have touched I can not assure nor give a percentage... Hope it helps, Samuel. 2006/7/6, G.Jacobsen < g_jacobsen(a)yahoo.co.uk >: Samuel, Do you happen to know what percentage of UAs out there are really "Compliant" UAs ? My impression so far regarding SRV DNS records is that they are theoretically a nice feature but unfortunately almost useless since one needs to cater for those non-compliant UAs anyway. I would love to be convinced of the contrary. Can anyone supply real usage figures regarding compliant/non-compliant UAS ?

Cofigure two SRV entries in your DNS, one pointing to the UAS SERver and another to the UK server. "Compliant" UAs will try to contact the other proxy upon failure of their current one.
