Hi, simple question :

- Main SER running on 5060

- Second SER instance running on 5090 to work with SEMS for Voicemail.

When a call arrive on the main SER:5060 and that is redirected to Voicemail, does my customer USER AGENT need to be able to connect to the 5090 port ?

Do i need to open this port ? Or it is the main ser instance that negociate with the SER:5090 ??

thanks
