Vicidial Expert Needed to Fix 20 Sec Call Drop

I need a Vicidial expert with in-depth knowledge of Vicidial/Asterisk and AGI script to help me troubleshoot a problem with my system. Currently, when a call comes in to a DID, it enters the queue and waits to be answered by a telecaller. However, after 20 seconds, the call gets disconnected automatically. Your task will involve: - Diagnosing and fixing the 20 seconds call drop issue. - Making necessary adjustments to the /etc/asterisk/[login to view URL] file. and agi script /usr/src/astguiclient/trunk/agi/[login to view URL] I believe the following lines may need to be removed: ; DID forwarded calls ;exten => _99909*.,1,Answer() exten => _99909*.,1,AGI([login to view URL]) exten => _99909*.,n,Hangup() Skills and experience required: - Extensive experience with Vicidial and Asterisk. - Proficiency in AGI scripting. - Prior experience in troubleshooting similar issues.
