After setting up Kerio operator, users started to complain that some extensions have delay (5-10 seconds) before phone starts to ring. It does not happen with all extensions.
After some testing, I figured out that it happens only with two digit extension that have the first digit the same as the first digit in three digit extensions.
For example, if you setup 3XX extension, then all 3X extension will have delay. Once I removed all 3XX extensions, all 3X started to ring without delay. The only problem is that I still have delay with 1X extension, even though I have no 1XX.
I wonder if there is a way to control how long system can wait for full extension to be dialed, before it starts to ring. In other words, how long should I allow system to wait for user to dial phone number or extension.

the Operator doesn't wait, the phones do. They wait usually 3-5 seconds before dialing the number to let you enter all the digits.
When you use auto-provisioning (screen phones) the phones are provisioned with a dialplan. A dialplan basically tells them that when a number starts with a "3" it will be followed by only one digit. A phone can then dial straight away skipping the inter-digit timeout.
When you have a 30 and 310 numbers in your dialplan, the phones have to wait for all three digits before dialing.
a) Review the Dialplan screen in Operator and make sure there are no 1xx or 1... numbers there
b) Modify the phones' dialplan to fit your needs. Either by their web administration or by modifying the provisioning files
c) Lower the phones' interdigit timers. Note that your users might not be quick enough to enter all digits when dialing.
If you think that the dialplan is not generated correctly, please:
1. Enable the provisioning debug log (right click on the debug log screen)
2. Restart some of the phones, wait few minutes
3. Download a support info file (link at the bottom of the System Health screen)
4. Download the phone configuration (right click on a phone and select "Download original configuration")
5. Email everything to fjenicek<_at_>kerio.com
