OK, thank you very much. I could easily delete "UPDATE, " in "allow:" field 
sent by FreeSwitch using SIPProxy http://sourceforge.net/projects/sipproxy/
since I already used SIPProxy to modify messages sent by other clients like 
Linphone, but I can't figure out what I have to set in FS to have all SIP 
messages sent and received through SIPProxy.
In a client like Linphone, this setting is easy :

[proxy_3]
reg_proxy=<sip:192.168.1.6:5064>       # SIPProxy IP:port
reg_route=<sip:192.168.1.6:5064>       # SIPProxy IP:port
reg_identity=sip:0033972XXXXXX at sip.ovh.fr

But how to set reg_proxy and reg_route or equivalents in FreeSwitch ?
