[Serusers] Packets fragmentation and message reduction

I found a situation where some SIP phones worked and some don't. After a while I found that, because of the added bytes of the "Proxy-Authorization:" header, the messages generated by some sip phones were larger than 1480 bytes and this caused the connection with the PSTN gateway to not work. I tried to forwad the message with the t_relay_to_tcp() function, but by the ngrep output it seems that it still uses UDP (but I may be wrong). Anyway, what can be done in this situations? What about a SER module that rewrite all header field names with their compact form? Often, the message is only a few bytes more than 1480, so this could be a solution... What do you think?
