Hello,
I've got an AS5350 receiving calls on ISDN E1 and forwarding calls to
OpenSER. At the moment ENUM translations are performed on the AS5350 and
calls received by OpenSER already contain the correct SIP URIs.
Unfortunately I verified that the called party number information is
lost in the process and at the called side I cannot distinguish numbers
if I associate multiple PSTN numbers to the same sip user.
I guess this is Cisco's fault, since it should add a Remote-Party-ID of
type "called" to the INVITE. Do I have to move ENUM mapping to OpenSER
or is there a quicker solution?
thanks
Luca

Hi Luca,
if you cannot configure the Cisco GW to provide the original called
number information, the logical solution is indeed to move the ENUM part
on the proxy.

I haven't yet been successful in finding any reference on this issue in
the Cisco docs. Since the AS5350 is basically acting as B2BUA it may not
be able to behave like I want it to.
If I understand the ENUM module docs correctly the ENUM lookup from
OpenSER should replace the Request-URI while leaving the To header
untouched, so that the call will be correctly routed to the SIP user,
but will still preserve the information on the original called number.
So manually adding a Remote-Party-ID header for the called number should
not be needed.
ciao
