HI,
i got a problem here and i need your help.
I got 2 brand new VVX501 and using them in BaseProfile "Generic". In our Network we have also VVX401 which working flawless.
The Problem of the VVX501 is that we can't make Outbound calls (i don't even get dial sound). The phone has a successful registration to the pbx server. I can make intern calls (withn in our company).
The configuration of the 501 (simple setup) is the same as 401. On both models we are using
5.6.0.17325 Software. The other 501 we also tried the lastest softwareversion.
The odd -> When I am calling my 501 with my mobilephone I can pickup the call. If I recall the number on 501 in the history I can make the outbound call. When I am look the dialnumber closly it has a following format: sip:+43123456@ipadress_of_pbxserver.
In the other hand the failed outbound calls has a format of +43123456 (without sip: and pbx ipadress)
It seems that the phone has problem to "build the string" How I can teach the phone that he should the right thing?
Thanks.
