[Serusers] Setting maxfwd to 1 in single SER env?

[Frank Fischer]

Hi

I have a single SER wiht some clients and a PSTN gateway. Forwarding calls
over the internet to other SIP proxies is not possible/allowed. Now i
wonder, if i could compare the mf_process_maxfwd_header() with 1 since - if
i understand that concept right - there will always only be one hop needed
(eihter client to client or client to pstn gateway). 

Do i get this right or am i missing anything important?

Greetings
Frank
