Hello,

can a SRV record and an A record co-exist ?

Can I have both :

sip.domain.tld.    A    XX.XX.XX.XX
_SIP._udp.sip.domain.tld  SRV 0 1 5060 sip1.domain.tld.
??

Will IP-phones that support DNS SRV take the SRV-record and phones that 
do not support DNS SRV the A-record ?


If I only have :
_SIP._udp.sip.domain.tld  SRV 0 1 5060 sip1.domain.tld.
_SIP._udp.sip.domain.tld  SRV 0 1 5060 sip2.domain.tld.

what will happen with IP-phones that do not support DNS SRV when they 
register to sip.domain.tld ???


Kind regards,
Jonas.
