Hi all, I'm having a problem with extensions at a remote location. The 3CX server is at a main office and the extensions in question are at a branch office about 10 miles down the road. Both sites are fed by FiOS and connected by a Watchguard branch office VPN setup. The majority of the handsets are Cisco SPA504 or 508. The problem is intermittent, but seems to affect all extensions at the remote location to some degree. When it occurs, any call in or out results in chopping or cutting out or whatever you wish to call it for the user at the branch office. However, the person on the other end, whether at the main office or external, has no trouble hearing at all. It's most perplexing, and since it is intermittent, one-way, and there are a lot of components involved, I'm not quite sure how to approach troubleshooting. Any light that anyone can shed would be most appreciated. Thanks!
