------------------------------------------

Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.

> If an outbound registration is performed the update of the registration (to keep it from timing out) is not done to the same network address as the initial registration. If more than one host is present in the SRV record, the outbound update of the registration is sometimes done to a different host.
> RFC 3261 (SIP: Session Initiation Protocol) states in Section 10.2.4 (Refreshing Bindings) that “(…)Registration refreshes SHOULD be sent to the same network address as the original registration, unless redirected.”.
> So subsequent registration requests should always reach the same host.
> The provider in question uses the following SRV-Records (redacted):
> {code}
> _sip._udp.phone.provider.example.   5452    IN      SRV     10 1 5060 phone-a.provider.example.
> _sip._udp.phone.provider.example.   5452    IN      SRV     10 1 5060 phone-b.provider.example.
> {code}
> As the following two `REGISTER` messages show the first one is sent to phone-a (IP: XXXX:7::10) the update for the registration is sent to phone-b (IP: XXXX:8::10):

> In my case the new registration to a different host leads to currently running calls being terminated.
