Hi Guys,
We have the following topology:
SIP PRXY ---- CS1K(1)---- NRS ----- CS1K(2)
The SIP proxy we use isn't able to communicate with the Nortel NRS (redirect mode), so we use the CS1K(1) as tandem PBX -- all the SIP signaling between the SIP PRXY and the CS1K(2) goes trough the CS1K(1) --
The problem we have is that in an attended call transfer when the transferor and transferee are owned by SIP PRXY and the 3rd party is owned by the CS1K(2), when the transferee sends the INVITE to replace the dialog between the transferor and the 3rd party usign the CS1K(1) as tandem the CS1K(1) do not fw the INVITE wirn Replaces header to CS1K(2) so the transfer isn't performed (all the other signaling to stablish te previus dialog is fw ok).
Do you know if it could be a configuration issue in CS1K(1) ? Or it is a design constraint and cannot be resolved.
Thanks.
