Customer Premise Firewall/Router Recommendations
by justin＠ejtown.org March 4, 2012

March 4, 2012

I am in the position of needing to recommend a line of SMB (10-50 person offices) router/firewall devices that will play nice with VoIP. Specifically, office has phones (generally Cisco SPA's) connecting to remove service provider Asterisk servers. Historically, I've stayed out of the hardware on the customer side, but the growing presence of "stuff that breaks SIP" is leading me to pick a vendor. I generally am in the "don't touch my signalling" camp (read: no ALG). Is there a single vendor that is consistently good about not mucking with things too much? -jbn

Enterprise customer desiring NAT for their SIP
by frnkblk＠iname.com Feb. 28, 2012

Feb. 28, 2012

We have an enterprise customer that wants to trial our SIP trunking service. They're using Cisco Call Manager v8.5 and I tried to get them to use a public IP or a private VLAN to our network, but he insists that they want to keep their CCM behind their NATing firewall. Our softswitch has an integrated SBC, so our side is covered, but I'm afraid that they may run into some issues that are related to NAT but that we'll be held responsible. Should I continue to push back on this customer, or let them go down this road? Regards, Frank

e911 warning stickers on phones
by carlos＠televolve.com Feb. 24, 2012

Feb. 24, 2012

I'm trying to figure out the FCC requirements for 911 service warning stickers. The FCC documents are rather vague. They say a sticker is required "if there are limitations to the provider's 911 service" but then don't define what constitutes a limitation. Is the fact that the end user can move a handset a "limitation?" Is the likelihood of a power outage also causing a phone outage a "limitation?" So I'm wondering what other hosted service providers are doing? Also, if you provide SIP service to on-premises equipment, do you ship a huge batch of stickers to the customer? Or just include an e911 warning in the contract? Wording of stickers? How do you make them small and unobtrusive on a phone? I considered something that goes under the handset, but that's a small space. Is "E911 WARNING: See this URL" going to be sufficient and compliant? -- Carlos Alvarez TelEvolve 602-889-3003

Call Rate Limiting / Blocking (AcmePacket + Broadsoft NS)
by keith.croxford1＠gmail.com Feb. 20, 2012

Feb. 20, 2012

I'm looking for input from other voice providers: We have an off-net number that periodically floods our network with inbound calls. When this happens our NS ( Broadsoft) often reaches or exceeds the number of available licenses. The end result is that new call requests fail until the call volume decreases. This usually last for 5-10 seconds. We have a cluster of AcmePacket SBCs in front of Broadworks. Does anyone know if it is possible to limit the calls per second on a dynamic originating number? I say this as the originating caller might be 555-555-1111 for 10 minutes, then another flood of calls originates from 444-444-2222 a few hours later. We believe these to be from the same caller due to the IVR message presented. If it is possible would the AcmePacket SBC perform this as an HMR in software, or would the SBC hardware handle this? If the SBC cannot do this, is it possible to perform some sort of dynamic rate limiting on a Broadsoft NS and send a failure response code w/a reason code after a metric is breached? Any other suggestions would be great. The last question involves legal implication of blocking a number. Assume that we blocked all calls from 555-555-1111 at our SBC. Two weeks from now Customer A opens a trouble ticket that their customer cannot call them. Of course the company's main line happens to be 555-555-1111. Is there any FCC rule or regulation that would limit this. I'm trying to find something in Title 47 of the Code of Federal Regulations. Thanks! Keith
