Re: [Equipment] Useful Sipura tricks...
Here's how to take control of how often your adapter "registers":
I'm sure you all know about the "Register Expires:" parameter (on the "Line x" tab). This is supposed to control how often your adapter registers (the parameter is in seconds).
However, I have been trying to figure out why the registration interval could sometimes be a lot shorter, or a lot shorter than I supposedly set in "Register Expires:". I finally found some of the other settings (and other factors that effect registration). Here they are (as best I can figure):
It appears that the SIP provider you try to contact can override the registration interval (by the SIP messages they send when you try to register). This can greatly change how often you thought you would register...
To take control back, here are some other settings to adjust:
You can specify a MINIMUM normal registration interval, below which the provider can't register more often, by setting the "Reg Min Expires:" value (advanced "SIP" tab).
You can specify a MAXIMUM normal registration interval which you will always reregister by (even if the provider wants to register less often) by setting "Reg Max Expires:" (again, SIP tab).
In addition, the two parameters "Reg Retry Intvl:" and "Reg Retry Long Intvl:" (also "SIP" tab) seem to control how long you wait to try registering again, if a registration attempt "fails". This can be important, as you often want to try again "reasonably soon" if/when the registration has a problem and "fails". Because while you aren't registered, you aren't receiving inbound calls (and with some providers, you also can't make outbound calls when not registered). |
