<div dir="ltr">We had a customer that had Frontier Analog phone lines going into their Panasonic TDA-50 PBX system. We recently ported the numbers from Frontier to our Broadsoft, and deployed a Poly OBI508 ATA onsite. We also replaced their router and internet connection.<div><br></div><div>Customer is complaining that their phones are displaying the wrong time. We explained to them that we did not mess with their phone system PBX only the input lines.</div><div><br></div><div>My question is, do oldschool, onsite PBX systems, like a
Panasonic TDA-50, use the analog FXS input lines from the provider (us) as a timing source? If so, what protocol is this, and where would be change it on the adapter? </div><div><br></div><div>I would think most PBX systems are like computers, and would use NTP as the timing source. </div><div><br></div><div><br></div></div>
