When I call from a Lync client I can make a call to the PSTN through the PBX, but when I try it in Lync Mobile 2013, I type the number, I can even see it being normalized on the screen, but it can't make call.
I don't know if there is a change I have to make so the call can pass, because, as I told you, I see in the screen of the iPhone the number normalized, but the call isn't made.
Thanks in advance.
