Hi,
I have setup a site to site vpn from my HO to Remote site. In HO I am using CUCM 8.6 and ASA 5525X. On Remote site I am using Cisco 887 va router. The tunnel is setup between ASA and Cisco 887 va router. The Data is working fine no issues in it. But when I try to connect cisco 7911 phone on Remote site it can dial mobile phones and there is no problem. However, when it try to dial internal number in HO call is connected and i can see that call gets picked up but there is no voice at both ends. From the router I can ping the CUCM ip address, and when I try to ping from esxi (on which CUCM is installed) to the default ip of the router it fails. Any idea what is going on? Please see attached config for router.
Thank you,
Kind Regards
Rohit.
