Sorry if i come across quite incompetent it is due to me being thrown into the deep end with no Asterisk training or background support at all.
One of clients is currently experiencing an issue where 3 extensions are unable to make calls out transfer or dial internally.
I have attempted to reboot the server twice as well as restart the asterisk service itself once.
I have checked the outbound routes to make sure these appear correct but due to me not having any experience with Asterisk i am not even sure this is correct.
We are currently using Trixbox.
Unfortunately i really cant tell you any more than this due to me not knowing the information. If somebody is able to help it would greatly be appreciated.
