Cisco ISR4331 with GrandStream UCM6304A connection

[Mo7eid]

Hi,

I need your support to configure SIP trunking communication between Cisco ISR 4331 with GS UCM6304A.

SIP trunk is configured in the UCM6304A, but I can't do it for the Cisco SR.

attached is the Cisco 4331 license.

can you guide me with the steps.

Appreciated

WE normally do that using CLI. You need to create Dial-peers pointing to the Grand stream. 

Refer the below guide.
