Hello friends… i have the following issue, recently i have purchased a SIP trunking service with a local provider, he has a Cisco 7206 and is sending me the calls via g729 codec. I have setup the trunk and i can make outbound calls without problems, the problem is when i do an inbound call, the internal phone rings well but when i pick up the phone the call is finished with: Got SIP response 486 “Busy here” back from xxx.xx.xx.xxx i thought the problem was with the free g729 codec then i ask my provider to send me the call via g711 to test, and with this codec the inbound call was made without problems, then i buy a g729 codec licence from digium to test and to know if the free codec has this limitation but not, the result is the same, and really i don’t know what to do, i was looking for information on the web but there is nothing, some people have the same problem but almost there is no response…
Thank’s in advace…
