I have a customer have a Comdial system. I only support Allworx and Adtran PBX. In a nutshell, the problems we are experiencing boil down to:

#1- multiple dropped calls almost daily on any of our extensions, most consistently (but not exclusively) on incoming cell phone calls;

#2 – numerous complaints that our outgoing conversations/recorded greetings are faint and of otherwise poor quality;

#3 – calls being randomly re-routed to wrong extensions or possibly our fax line.

Please give me a call anytime 949-394-0263
