Hi all, Polycoms have two locations for setting the Outbound Proxy. The first is a per-Phone setting on the "SIP Servers" screen. The second is a per-Line setting under "Lines" -> X -> "Registration" (and "Show Advanced Settings".)
Chris recently asked me which one should be adjusted in the case of a Remote Worker Phone. The correct answer is the per-Line setting. This is because a non-blank per-Line value overrides any per-Phone value, and with XCF-1614 the per-Line default value is now the Line's SIP domain (i.e. non-blank.) The problem is that the GUI tempts you to configure the per-Phone setting, which is wrong: - A superadmin who starts looking will almost surely find this setting first, since it isn't buried under Lines or tucked away under Advanced. - The default value is currently blank, which might lead you to believe you can simply fill in the desired Outbound Proxy value and be done. - The help text doesn't give you any indication that the value will be ignored because the per-Line setting is non-blank. We should fix this. But rather than directing the superadmin to the hard to find setting, let's turn the easy to find setting into the correct one. In most cases a Phone will only ever need a single Outbound Proxy, so let's use the per-Phone setting. i.e. The SIP domain of the first Line is used as the default per-Phone value. All Lines using this SIP domain will have a blank default per-Line value, so that the per-Phone value is used instead. Occasionally a Phone will also have an External Line, which means a different Outbound Proxy will be required. In this case the per-Line default value will be the SIP domain of that Line, so that the per-Phone value is overridden. (Help text will be added to the per-Phone setting indicating a non-blank per-Line value takes precedence.) For a Remote Worker Phone the superadmin will only need to adjust the single per-Phone Outbound Proxy value, which is easy to find. In rare cases a Phone will have an External Line where the default Outbound Proxy value is not correct. But even in this case I think the correct action will be intuitive: The External Line's Outbound Proxy value must be changed, not the per-Phone value. I think this approach will make the typical Remote Worker case considerably easier, without introducing any confusion to the rare case. Thoughts? -Paul [email protected]
