[Serusers] sequential forking and merged request

Hello, 
I have a question about sequential forking and Merged Request.
If in a forking SER calls two lines of the same client (different numbers and different Request-URIs) it refuses the second call with 482 (Cisco and Snom multiline phone for example) according with RFC 3261 section 8.2.2.2 because the two INVITEs have the same Call-Id, From tag and Cseq.
If this behaviour is reasonable with a phone, it could not be acceptable for other types of client, first of all SIP-PSTN gateway.
Is it correct this RFC interpretation? Maybe is this section inappropriate for gateways?  
Is there something that I can do in the config file?
