If someone can help it will be very much appreciated as I have come to a stop with the support from voipo.
1 I repeatedly indicate to them that the ports that want are all fo forwarded to the sip device they keep sendig same canned email
2 I have issues only with few phone #'s that I call all other they work fine
3 phone #'s that I call and have issues are dead air on termination call some times get an aswer but the cuts off
4 I have perform the ping test as they have requested with good results and now we are back to have the ports open please see number 1
I truly dont not know what is the next step
Thank you
