Hi there,

does anyone know if cisco implemented ISDN subaddressing with sip (rfc 4715)?

I've tried isub but it doesnt work?

Is it possible there is some other sip header for that?

What we are interested in is Calling Party Subaddress, and Called Party Subaddress, encoded with BCD.

Or should we go with h323? (puke)

Thanks in advance,
