I hope someone can help me out here, basically when i make a outward call to any mobile phone I cannot be heard by the person who is answering? I have tried calling O2, Orange and Vodafone networks in the UK and also abroad.
I have added £5 credit so I know that should not be the issue, any ideas? Landlane calls seem to be fine?
I have a recently added the pbx package but I am unsure how this could effect this problem. I am using a Linksis spa491 phone which works great, I just hope i'm missing something big here? This problem is not a one off either as I noticed this a few days ago just put it down to a temporary blip.
Any support will be very welcome.
Ok this is now fixed, in-case anyone is interested or has this problem in the future I changed the RTP parameters on the phone to 8000 for the max rtp port and 8000 for the min port also.
