<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:10pt"><div>We are working on a new channel driver, which is more of an analog driver. When originating a call using this new driver (incoming) to a SIP end user (SIP Channel driver is the outgoing channel driver) the SIP Channel Driver does send out to its endpoint the SIP:INVITE, and received the SIP:1xx messages including RINGING. The 200OK comes into the SIP Channel Driver and SIP:ACK sent out to the endpoint. BUT THE ISSUE IS THIS: Ringing still continues on the line and does not stop, event after answering so it is not possible to talk.<br></div><div><br></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;">How to stop ringing? What needs to be done to ensure that Ringing is not longer applied to that endpoint?
A SIP call to SIP call works fine through the SIP Channel Driver. </div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;"><br></div><!--[if gte mso 9]><xml>
