Hi Simon,

to force sending from a different interface (to switch across the interfaces), use the force_send_socket() function. See: http://openser.org/dokuwiki/doku.php?id=openser_core_cookbook#force_send_socket_protoaddress_port

the double Record-Route will automatically be inserted to reflect the interface change.

regards,
bogdan

Hello there,

We currently have the following configuration. An openser is listening on two
interfaces. One is linked to an internal private network, on which
users (sipphones)
are. The other is link to a public network.

We noticed several issues :

- When an INVITE (for exemple) comes from the private network and has to be relayed to the public network, openser put the private address as the source of the outgoing message. (sendto() use the same socket from which the message
came from ?)

- To solve this issue, we set up openser to listen on 0.0.0.0 (only
one socket) but
with this config, openser was unable to put the correct address into
'Record-Route'
headers. (i.e. Record-Route: <sip:0.0.0.0:5060> !)

Is there a specific way of setting up openser in a multi-homed situation ?

Thanks in advance.
