Hello,

Thanks for the response. But who is generating this
problem, the Cisco or the ser server? If I make an ip
call between the tow ata's everything works fine, so I
belive that the server is the problem. According to
RFC3262:
"The UAS MUST send any non-100 provisional response
reliably if the initial request contained a Require
header field with the option tag 100rel. If the UAS
is unwilling to do so, it MUST reject the initial
request with a 420 (Bad Extension) and include an
Unsupported header field containing the option tag
100rel. "
So, if the ser proxy will give me a 420 error with
unsupported header field and not a 400 error the ATA
will not require any more 100rel. Am I right?
