I have a J179 SIP Phone set up at a remote location. It is tied an IPO at the main office. Licenses are not the issue. We have plenty, plenty of voice compression etc. We have the same set up from several locations. WE HAVE NO SOUND EITHER Direction from this location.
From this problem location, the phone logs on immediately and registers. The phone lights up with the buttons as programmmed. Correct extension shows. I can use the diretory and place calls, and calls to unanswered calls are transferred to Voice mail. All legs in these calls are logged by XIMA. But no voice
The switch on the remote end, has zero firewalls or blocking issues built in. We have tried this hardware at other locations without success. I can plug the phone directly into the switch at the main office and have no issues. On site everything is fine, except no sound. I have changed the direct media path to checked and unchecked. i have compared settings from other working phones, but have found no discrepancies. Is there a setting i am missing somewhere that would cause this? it is driving me to drink!!
