Are there any special considerations when using Fring?
Yes. We've seen an issue in Fring's software (at least version 4.0.0.9) that causes Fring to be unable to register (connect) to our network due to how it responds and sends SIP messages. We are attempting to get this resolved with Fring directly, however as a workaround you can do the following which should resolve this issue:

When configuring Fring to use Callcentric, instead of entering "callcentric.com" within the Proxy field, instead enter "fring.callcentric.com".

Using "fring.callcentric.com" as the Proxy should allow Fring to connect to our network and place and receive calls.
