Thank you for your contribution, unfortunately this problem is not going to be resolved through the normal elementary issues. I am well aware of the need to use T38, and the codec is alaw. I have already covered my bases in advance of coming on this list making my statement- 1. Hardware is fine - CW works 2. Firewall rules are fine - CW works 3. Link is fine - It's fibre 4. Provider supports T38 Further in response to Steve's comment - I have contacted my up line provider and they have advised me that they use Asterisk at their end. I am still waiting for advice as to 'what' T38 fax solution they are using, though at this point it's looking less likely that it is compatibility issues.
