Hi Hanifa FQDN "p1-cscf.open-ims.test" resolve to 3 IP addresses is perfectly fine. Ideally you need to take the preferred IP and use.
For more details you can refer "Locating SIP servers" RFC 3263.

Hi all, Can a FQDN "p1-cscf.open-ims.test" resolve to 3 IP addresses as below? 1. 172.16.8.10 - UDP and no signal security support 2. 172.16.8.20 - UDP, TCP but no signal security support 3. 172.16.8.30 - UDP, TCP and signal security support [TLS] We feel that all the resolved IP addresses of an FQDN must be of same configuration. Pl clarify. If the vendor wants to have P-CSCF with different configuration, then FQDN has to be different.
