[Freeswitch-users] Freeswitch stop working error 900

[cjbujold at accra.ca]

Freeswitch has been working for several months with no problems.  This 
morning we walk in and it will not connect to our gateway. Keep getting 
Fail_Wait error.  When we look at the log we get the following error:

[ERR] sophia_reg.c:2236 mountain Registration Failed with status 
Internal error at nua_client.c:550 [900].

How can we fix this error?

Thanks
