It is a bit tough. There are some special headers added, but they can be
changed or removed (e.g., server, warning). If you have an account to
that server, it is easier, because you can watch traffic in a call.
Early versions of openser used same phrase in 100 reply from TM. Now
they are different, but not the "Trying" as in RFC.
Also, building branch value in ACK is different in specific situations.
I d not remember all differences, but with a bit investigation some
criteria can be found.
Cheers,
Daniel

It'd be interesting to be able to identify either
... like nmap tries
to do with the end OS ... but knowing whether it is a ser or openser i
guess it would be a nice first step ... :)

Hello
Is there a way to know which commercial SIP servers are based on
openser or ser?
Or if a specific SIP server is based on openser or ser?
:-) you want to
differentiate between openser and ser, or between
openser or ser and other SIP servers?
Cheers,
Daniel
Thanks.
