Telephonic is proud to be the primary Canadian partner providing SIP trunks for users of Kerio Operator. 

Starting in June 2012, Telephonic and Kerio's Brian Carmichael completed inter-op testing and configuration of Telephonic's active-active failover SIP trunks with Kerio Operator.  Brian was kind enough to provide a configuration guide for Kerio Operator users with Telephonic SIP trunks. 

In March 2014, Telephonic and Kerio have collaborated to enable new T.38 faxing support on Telephonic SIP trunks and Kerio Operator. Telephonic has updated the SIP trunk configuration guide for Kerio Operator with a step-by-step video (see below).

 Telephonic is happy to provide a $5.00 credit trial account so you can see how great our SIP trunking is. To claim your $5.00 credit and get your own SIP trunk registration credentials, please complete the below form.
