Hello all, I am working on an outbound proxy configuration and here is my setup. UA ------> Outbound ------->firewall(NAT) -------->Proxy. Both UA and outbound are behind the NAT. I did some RFC study on outbound configuration for routing calls both inbound and outbound through outbound proxy. According to RFC 3327 Extension Header field for Registering Non-Adjacent contacts, PATH variable has to be introduced into REGISTRATIONS. Here are few questions and any help with answers is greatly appreciated. 1. Default openser.cfg will route request to destination if (URI != myself) and appends p-hint:outbound. What exactly is the significance of P-hint:outbound? http://tools.ietf.org/html/draft-ietf-sip-outbound-15 says ob parameter has to be added to PATH filed or Contact Field to retain path.  P-hint got to do any thing regarding this? 2. I enabled path.so module. But  openser does not at PATH filed to outgoing requests. Can someone direct me to a config example? Thanks in advance, Sid
