[SR-Users] possible bug on {param.value,name}

Tue May 4 16:29:06 CEST 2021

Hello Daniel,

Yes, initially my question was about the tcpops returning an error, but
then i realized i was passing the parameter as it was returned by

$var(conid) = $(hdr(Route){uri.param,wsconnid})

Which had an extra ">" at the end.

But the problem wasn't really with the tcpops function, but with the
transformation.

Thanks for taking the time to read the emails :)

Regards,

David Villasmil
