Incoming Calls Die on Hold
Incoming Calls Die on Hold
I've got a little bit of an issue that I'll describe as best as I can. I'm a tech guy by nature, but telecom is not my top skill. long story short, I found the BCM system and spent what seems like forever learning to configure this system, all was working well with a couple issues. I'm only going to describe the biggest issue I'm having here, and that is that the minute I put an incoming call on hold, it's dead; but this only happens on my system.
Here's the setup that I've got going on.
BCM50 r6 fully patched with an SSD in place of the original HDD at both my mothers house and mine, each system is configured identically, and I've spent a couple hours making sure that both of our systems are configured exactly the same. Her system does not have any of the symptoms that I'm describing, everything works as intended at that location.
Our systems run pfSense for routing and VPN between the two locations and the main switch for both locations is a Nortel 5520 series. The system is configured so that when a call comes in on the sip trunk, it heads to a hunt group where both the kitchen phone and my office phone ring. Calls are set to automatically associate to a SWCA key on hold. Here's what happens: I get an incoming call, and everything works fine, but if I put the call on hold, there's no hold music; additionally, when I hit the "Call 1" key to pick the call back up, there's dead air, and the other caller can't hear me nor can I hear them. The issue is the same if I do an exclusive hold to an intercom key. This doesn't happen with calls placed from site to site through the VPN, only with calls from the external provider. (flowroute in this case.) If I transfer that dead call out to another number, everything works just fine and audio resumes. Outbound calls work just fine and can be placed on hold with no issues. This is a new issue, and it was previously working just fine, but one day this issue cropped up and I've been unable to resolve it on my own.
When this happens, the call is still seen in BCM monitor. This only happens with IP sets, I plugged an M7324 into the system during troubleshooting and it functions as intended, calls get placed on hold, MOH works and when picked back up, everything is fine. I'm using 1140e's everywhere in the house.
I've been through all the options in element manager, scoured the logs, I've factory defaulted my network switch, changed ethernet cables, tried it with an i2004 all with the same result. I'm this close to L2 resetting the system and building it back from scratch, but I'd really like to sort the issue out instead of taking the easy way out.
Anyone have any ideas? This isn't the first issue I've had with this system regarding dead air, I originally had FM/FM in the mix, but that just rings my cell phone and nothing is there when I pick it up so I've disabled it for now. I don't generally ask for help until I'm sure I can't resolve an issue on my own, and my next guess is that something is wrong in the system software somewhere, but I figured I'd ask for the professional opinion first.
