CUBE with Dual SIP trunks on single Gig inteface.

[Ritesh Desai]

Hi folks,

I ran into a situation where customer has single ISR 4331 router with total 2 SIP trunks from different telecom providers. on ISR 4331 by default loaded with 2 Gig interfaces. As best practice, is it recommended to have single Gig with 2 different SIP trunks in contact center environment with 150 concurrent calls on single CUBE.

i just thought of setting up sub interfaces on gig port and bind the control and media respective to each SIP trunk WAN port for call routing. 

I just want to follow correct industry standards and implementation ease approach avoid complex solution.

Has someone done similar sort of implementation? 

with regards,
