...in the host box. Putting registrar.provider.com in the register => string and nat.provider.com in the host makes outbound calls fail, putting registrar.provider.com in the host and nat.provider.com (with or without the :5065) in the registrar doesn't allow incoming or outgoing calls putting reistrar.provider.com in both host and the register => string allows outgoing but not incomming firstly, what does the outbound proxy do? secondly, can anyone advise on settings for this senario? does asterisk have this concept in its SIP client? Thanks David
