A strange one

[cpjitservices]

Hi all,

 

I have a client in Europe. We are trying to change routers for the network which this client has set up, currently they are using a Cisco router. They have on Site a PBX. Trying to install a Draytek router, usual setup its on the same subnet as what everything else is configured as. The PBX has multiple interfaces on the same IP Range, Don't know why but thats how it was setup with the Phone Company. Put in a Draytek router and the PBX cannot be pinged on one of its interfaces which means no Audio on incoming calls. Put the Cisco back in place and all is well within the world, phone calls as you would expect.

 

Heres the strange part, Draytek cannot and will not speak to the PBX on one of its interfaces as stated, Cisco back in place can ping every man and his dog, plug a PC into the PBX can talk to all Interfaces.

 

UHHH

 

Any Ideas why the Draytek has taken offence ? This is the 3rd different model of the Draytek we have sent to the client to test.

 

Stuck.

 

Draytek drawn a blank, Phone company have drawn a blank also.

 

Thanks all.
