Cisco ISR C1117

Hey guys,

 

We have a test lab in our office where we used to work with a Cisco 887va on a VDSL circuit.

Now we have a new setup with a Cisco ISRC1117-4PLTEEA on the same circuit. 

The latter is using IOS-XE.

 

Everything works fine except for the voip phones. They cannot provision anymore. Showing "no service" on the display. They do receive a IP-address via DHCP. They connect to a Asterisk based PBX external. 

 

So basicly the config is the same like it was on the 887va, but I have no idea why the phones are not registering anymore. 

 

Anyone in the same boat on this? Suggestions much appreciated :)

Thank you.

Hi,

Are you using firewall on the router? is there any port forwarding and is it same as 887?

 

Thanks

John

hi John,

 

no the ZBF is not enabled, just ACLs which are the same as the 887 router. 

There are no port forwardings..
