Hi,
I have just setup BT Cloud Voice which is a voip phone system and a BT Business Hub 5 router. I plugged the hub Ethernet cable into a wan port on the peplink and then another Ethernet cable from the peplink lan port to the voip powered switch. Problem is the voip provider tells me the BT Business Hub 5 router is on the wrong side of the firewall and its causing a lot of lag.
Can anyone think of a way around this problem please? I have gotten used to the security of both a second internet connection and a 3g dongle clicking in if there is an outage.
To get over the problem so far I have had to plug the router directly into the switch. The voip provider has confirmed the lag has now gone.
Thank You
Paul
Hi TK Liew,
-
I think so, I bought it about three years ago, it has 2 wan ports, 1 usb port and 4 lan ports. Sorry I can’t check because I am off site right now. I remember it was the entry level model at the time.

With the fibre we get 40 meg download and 10 meg upload

I have not checked this, but BT must have been able to ping the system as they said when plugged in to peplink the reading was about 3400 and when the router was direct to voip switch it was 120

Sorry don’t know

No it is all the time, even with low usage

Yes, the BT support said it showed as a SIP gate ALG fault. They got me to check the BT router settings but the setting was already set to off which is correct. Here is there page on the issue: http://btbusiness.custhelp.com/app/answers/detail/a_id/34573/~/what-is-sip-alg-and-how-can-i-stop-it-causing-problems-on-cloud-voice%3F
Further information is it is a five voip system and about 6 computers. We tend only to have two or three calls going on at any one time. The computers do not do any heavy downloads just access our cloud database which is only light network traffic.
Thank You
Paul
In the Balance Router, go to Network>Service Passthrough:SIP: Ensure that Compatibility Mode is selected.
Standard = SIP ALG ON
Compatibility = SIP ALG OFF
Thanks Jarid, I will test out when I am back at work tomorrow.
Are there any other settings I might need to look out for please?
Also I was thinking should I let the BT Router be the DHCP server or the peplink?
The BT Router is on 192.168.1.254 and the voip switch 192.168.1.1 what ip should I put the peplink on please?
Will QOS give me any problems please?
Thank You
Paul
Hi Paul,
Firstly, since the VOIP switch is provided by BT, please confirm with them whether this connectivity is valid. I assume IP subnet for Balance’s LAN = 192.168.2.0/24 and WAN = 192.168.1.0/24. Of course SIP ALG must be turn off on B210.
IP phones (192.168.2.x/24)–> VOIP switch (192.168.2.2/24) –> (LAN, 192.168.2.1/24) B210 (WAN, 192.168.1.2/24)–> (LAN, 192.168.1.1/24) Hub5 Router –> Internet –> SIP Provider
To ensure Voip traffics alway go through same WAN, please add Outbound Policy below.
