Hi Nitesh,
Happy Tuesday !
The Server setting in OpenSIPS impacts only the SIP messages generated
by OpenSIPS itself (while acting as Server), it does not impact the SIP
messages that are "proxy"ed by OpenSIPS - like the 180 reply you mentioned.

Hello All,
Happy Friday!
So while checking something I noticed that my "Server Header" is
getting overwritten on 180 Ringing.
I have the default server header defined on
top, server_header="Server: Engineering Test". It shows fine on "100
Giving it a try" but it gets overwritten on "180 Ringing".
Example, PSTN --> OpenSIPS --> ATA.
- When the call comes in via the PSTN network, OpenSIPS replies back
with "100 Giving it a try" to PSTN and sends "INVITE (SDP)" to
registered ATA. On the reply back to PSTN it shows "Server:
Engineering Test".
- ATA replies back with "100 Trying" and "180 Ringing" to OpenSIPS.
The reply back from ATA on "180 Ringing" shows Server:
OBIHAI/OBi302-3.2.5.8732 which over writes the default server_header=.
- When OpenSIPS replies back to PSTN with "180 Ringing", it shows
Server: OBIHAI/OBi302-3.2.5.8732.
Any insights on how I can prevent this from happening? I want to keep
the default server header going out on the PSTN network.
Thank you in advance...
Cheers,
Nitesh
