I don't know what it is but I disabled SIP ALG on our touter/firewall and it worked!

I think in my version it's "UPDATE Supported" but I set that to Auto and it didn't seem to do anything.

Yeah, I see it here, http://www.devconnectprogram.com/fileMedia/download/c46c7053-b6b6-4915-a101-0828f9dfca80, but not in my version.

Version 8.1. Where is that setting located?

Did you find a solution to this? Having the same problem.

We have an IPO system with only one remote user who connects via SIP trunk (Flowroute). When someone calls him, the audio works fine in both directions but if they end up in his voicemail, they do not hear the greeting and he does not get any sound in the message (if they wait long enough to...

I should add that I'm not getting any errors in the Status panel but the line status does indicated SEIZED when the twinning call goes out to the cell phone.

Does the SMTP server allow attachments that big?

I have one remote user who access the IP Office system via SIP. He wants to twin his mobile phone for when he travels. When someone call him, the call goes through with caller ID but as soon as he answers it, the drops the call. We have 2 SIP Trunk Channel licenses and our SIP provider says...

Understood, we added back in a router and put the IPO in a DMZ.

I'm seeing the twinning occur over the other lines but it's only there for a few seconds before it shows "clearing." Why would it drop so quickly?

Maybe I'm using the term "analog" incorrectly. They are just not SIP lines. I had this working at one point last week but then a number of changes were made to the system.

I have one remote user that has twining setup. We only have one SIP trunk so I need the twinning to use one of the analog lines rather than try to use the SIP trunk as it wil already be in use when someone calls him. I've tried adding a 9 in front of his mobile number but it won't seem to go...

It IS passing traffic between the two networks. The Internet is only available on the PC LAN.

I'm no expert, which is why I'm on here but I'm not looking for commentary and analysis of the setup just a better understanding of the feature and how to properly use it. It seems to me that the difficulty around configuring the firewall policy is the reason people do not use it and not...

The PC LAN is LAN2 and the phones are on a separate VLAN (to segregate traffic) on LAN1 so this configuration will work and it does when I don't use the firewall policy. I already have the manual so cutting and pasting it here is not much help. It seems to me that no one really knows how to...

Thanks but I'm not really looking for opinions on the quality of the IPO firewall but instead how to properly use it. We have a hardware firewall already but I would still like to utilize the software firewall so that the IPO is not wide open on the LAN either.

I'm having difficulty with HEX notation of the custom firewall entries. I need to allow UDP 5060 through in both directions. It is my understanding that I would need to use the following: IP Protocol: 17 Match Offset: 16 Match Length: 2 Match Data: 13C4 Match Mask: FFFF However, it does not...
