I have problem not between Quintum and Cisco. I can obtained ring tone but the call dropped immediately when destination picked up, or sometimes, I got ring but no answer. I talk to many people. They said it might be the IOS version mismatch between CISCO and Quintum. Now, I am using IOS Ver. 12.3 at Cisco. I would like to know the IOS or CMS version of Quintum that match with my Cisco IOS.
If anyone have idea, please suggest.
Thank you very much
