VoIP engineer who designs, deploys and maintains call-centre and business phone systems on Asterisk, VICIdial and Linux.
About Saqlain
Saqlain is a VoIP engineer: he designs, configures and maintains business phone and call-centre systems on Asterisk, VICIdial and Linux, and works with Cisco Unified Communications Manager and RingCentral.
He has implemented and optimised call-centre solutions, customised dialers with PHP and SQL, and troubleshoots complex VoIP infrastructure down to SIP, RTP, firewalls and NAT.
At ZNova that means reliable voice for clients: new phone systems and call-centre dialers, and proactive monitoring and support for the ones already running.
He keeps up with open-source VoIP as it develops and likes making systems more reliable and workflows simpler.
