Cisco UC320W - Issues using remote phones over VPN

Sat May 07, 2016 1:02 am

Hi,

I am having issues using SPA504G handsets over a Sophos UTM site to site VPN from 'Site B'.

All handsets work perfectly at 'Site A'.

Handsets are on a different IP range but they can see/connect back and sync to the UC320W.

I am able to make internal calls but they only last 15 seconds then drop??

Unable to make any external calls. When I dial 0 for an outside line the handset says "InvalidNumber"

Setup details

Site A
UC320W LAN = 192.168.20.x
UC320W Voice = 192.168.10.x
UC320W WAN = 192.168.30.x

Site B
LAN = 192.168.40.x
Voice = 192.168.50.x

All IP ranges are routed/visible via the Site to Site VPN.

Looking at the logs on the UC320W the following sticks out as an issue.
