SIP Options and SIP Extensions

[ltxn]

Hey,

We have a customer with an IP500v2 (R8.0) on the main site and a 3rd party SIP extension on a remote site. Everything works but if the VPN goes down the SIP extension stops working too, only solution is to reset the extension.
We're working with the data provider to get the VPN stable, but in the meantime I was wondering if the IPO uses OPTION packets to verify if the link is up and how to modify the parameters?
Do SIP extensions use the same parameters as SIP Trunks?

SIP Options
IP Office sends SIP OPTIONS messages periodically to determine if the SIP connection is active. The rate at which the messages are sent is determined by the combination of the Binding Refresh Time (in seconds) set on the Network Topology tab and the SIP_OPTIONS_PERIOD parameter (in minutes) that can be set on the Source Number tab of the noUser user. The OPTIONS period is determined in the following manner:
[ul]
[li]If no SIP_OPTIONS_PERIOD parameter is defined and the Binding Refresh Time is 0, then the default value of 44 seconds is used[/li]
[li]To establish a period less than 44 seconds, do not define a SIP_OPTIONS_PERIOD parameter and set the Binding Refresh Time to a value less than 44 secs. The OPTIONS message period will be equal to the Binding Refresh Time[/li]
[li]To establish a period greater than 44 seconds, a SIP_OPTIONS_PERIOD parameter must be defined. The Binding Refresh Time must be set to a value greater than 42 secs. The OPTIONS message period will be the smaller of the Binding Refresh Time and the SIP_OPTIONS_PERIOD[/li]
[/ul]

Is it a third party SIP endpoint is it? The only options you have are whats on the phone itself, and under extensions, and LAN SIP registrar.

I think Options is trunk related only.
