Set the smsc-id (also the allowed-smsc-id) to the same value for both groups (i.e. both for transmitter and receiver) but use different smsc-admin-id names for each group. That way you'll have both sessions with the same SMSC ID and Kannel will know to correlate outgoing messages with their incoming delivery reports. Multiple SMSC groups with the same smsc-id are allowed in Kannel.

smsc-admin-id is described in "Table 7-1. SMSC Group Variables" in Kannel documentation which is where the generic parameters are listed that apply to every kind of SMS center.
