Hello everybody,

how can we force freeswitch to send invites to the ip address of the

We are running freeswitch at a gateway to Deutsche Telekom NGN Sip-Trunk.

Deutsche Telekom changes priority of the registration ip address very often.

The TTL of the SRV DNS records is 300 seconds only.

If we are registered to and DNS priority ip address changes to the invites go to and Telekom answers with SIP-Code

403 forbidden.

Is there a way to force freeswitch to ignore the DNS for the invites and
send them to the IP of the registrar?

At the moment we are running a script wich supervises the DNS and renews
regitstaration if ip has changed.

This is not really a solution, because there are some dead times.
