hello Team,
I have Cisco 2901 Voice gateway with EHWIC-4ESG card installed..
Because 2901 Gig0/0 and 0/1 , both port are utilized. thus I am terminating ITSP SIP trunk on EHWIC-4ESG interface installed on the router.
Routing I have tested, as per below thread.. Hope my solution would work.. Kindly advise..
