Hi all, This improvement request has been captured in XCF-3397: Polycom Outbound Proxy - use per-Phone settings for default when possible. Thanks.

Agreed, it should be easier to configure and find. In my case I have one remote worker with a phone registered via two different sipx systems. It is enormously helpful to have this easier to understand, though I think the help text provided actually needs to alert the admin to the possibility of the pitfalls of just such a configuration. We're in the process now of trying to understand why the remote line can register & receive incoming calls, but when dialing voicemail, it is not recognized as an internal line (user has to put in line & pin to check voicemail) and calls outbound via the ITSP have one way audio issues, when everything is privately routed via VPN and nothing is blocked. Even though it is set to use the correct outbound proxy for that account. So if everyone feels this is supportable, then it would be good to have a how-to guide on the wiki for those of us who still can't quite get it yet. Tony >>> "Paul Mossman" 02/20/09 8:56 AM >>> 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]
