[Freeswitch-users] Configure FS to reply with domain instead of with IP to: user at domain instead of to: user at ip:port

[Tzury Bar Yochay]

Hi all,

I would like to know what should be done in order to have FreeSWITCH
reply with domains instead of IP-Addresses.
In my server, DNS NAPTR & SRV Records are all set and working fine.
Clients are connected using our pjsip port for windows mobile where
transport=tls.

When we connect to a public SIP service (e.g. iptel.org) we get the
domain when performing INVITE request.
We want to gain this behavior in FS as well so it will reply similarly.

I am referring to the "TO" part in the message e.g. To:
sip:user at domain instead of To: <sip:user at client-ip:client-port>

see below our client log in both cases (iptel and FS)

thanks in advance for your help,
Tzury
