Network engineer to diagnose 3CX call drops using Patton T1 VoIP gateway
Budget: $15 – $25 USD
Customer installation consists of a 3CX PBX, Patton T1 VoIP gateway with 2 T1 connections for a total of 46 channels. Customer is experiencing that some incoming calls drop after a few seconds and 3CX reports "route busy". Have sent Wireshark captures to 3CX and Patton tech support and unable to resolve the issue. The problem could be the T1 provider. Need a network engineer to work remotely capturing SIP data and determine the cause of the problem.
