What is VoIP?

Voice Over IP or Voice Over Internet Protocol is essentially the technology that makes telephone calls over the Internet possible. Instead of using traditional phone lines as voice calls’ infrastructure, VoIP uses broadband connection for the same process.

What is SIP or SIP trunking?

Session Initiation Protocol refers to the signaling protocol used to establish sessions in an IP network. SIP trunking is another term that refers to VoIP service, where Internet based telphone service providers provide voice services to customers with IP PBX.

What is SIP origination/SIP termination?

Call origination refers to calls initiated by a calling party using a telephone exchange of PSTN, and reaching a VoIP endpoint. Call termination refers to the reverse process, whereby a call is initiated by a VoIP caller with a PSTN endpoint. CommPeak proudly offers carrier-grade voice termination, voice or voip origination solution, toll-free DIDs and wholesale SMS, among others.

What is DID?

DID stands for Direct Inward Dialing (or DDI customizable toll-free origination service for businesses, call centers and any other company in need of being accessible to its audiences.

Do you pass Caller ID? What method do you use?

CommPeak passes the customer’s caller ID to its carriers at all times. When configuring a SIP account (Setup -> SIP accounts -> Edit account), you can choose if you wish CommPeak to pass caller ID, restrict it or override it with pre-configured setting at the SIP account configuration. You can configure the account to respect caller ID based on SIP header “From”, “P-Asserted-Identity” or “Remote-Party-ID”.

Do you offer termination in every country?

Most definitely! We offer a complete voice termination service in practically every country. We strive to provide our customers with the best possible quality routes and reliable all-around service. For this reason we are the No. 1 choice of termination for VoIP providers, SMBs & enterprises, calling card operators and more business segments.

What are the supported codecs?

We support the following codecs: G.729a, G.711u/a, GSM, ADPCM, iLBC

What codec should I use?

For best sound quality and, assuming you have the bandwidth available, we recommend G.711u. However, you can still maintain an excellent voice quality and lower bandwidth usage with codecs such as G.729.

Can I use my wireless/satellite connection?

CommPeak’s termination service will work over any type of Internet connection that has relatively low and stable latency. Wireless Internet connections sometimes suffer from fluctuating latency and packet loss, both of which would cause sub-optimal audio quality. Most satellite Internet connections will have issues with delayed or choppy audio due to the inherent amount of latency.

Our recommendation is that you check the ping times to our POPs. We recommend an Internet connection with ping times below 230ms.

Can I download the rates?

Yes, at Pricing -> Termination, click on Download as CSV.

Where is my traffic sent to?

CommPeak SIP Termination is a proxy service. We do not absorb media. Your media is routed directly to the closest demarcation point of the carriers.

Do I have to manage load-balancing or failover across multiple IP addresses?

CommPeak utilizes a virtual IP at each of its POPs for high availability. However, in case the entire local network (AS network) goes down, it may be useful to use multiple POPs for higher redundancy.

What are the SIP proxies IP addresses?

CommPeak has a large network of globally distributed POPs. We recommend making a ping test from your own network where the media servers are located to find the closest POP to your network: – uswest.sip.commpeak.com – useast.sip.commpeak.com – tokyo.sip.commpeak.com – singapore.sip.commpeak.com – brazil.sip.commpeak.com – ireland.sip.commpeak.com. You can always use sip.commpeak.com which will attempt to determine the POP that is closest to you.

Due to technical limitations, it will not always return the best results for you. We are aware that not all SIP proxies support DNS-based configuration of peers, which is why we will notify you via email in case we plan to change an IP address for a POP. However, we strongly advise to use DNS based configuration if possible.

How up to date are the CDRs?

CDR records are accessible through the customer portal and are updated almost instantly, within minutes of call completion.

Do you support any SIP TLS/SRTP encryption methods?

CommPeak currently does not support encryption methods for SIP or RTP. However, we will soon be offering support for the following SIP TLS and SRTP. For ultimate RTP security, we recommend that customers use ZRTP lookup.

What does billing increment mean?

Billing increment is the way we (and the telecom industry) calculate our rates in order to bill your calls. For example, if you call the Unites States for 10 seconds, you will be charged for 12 seconds (call minimum is 6 seconds, and 2(x)6 seconds since this is a 6 second increment call), instead of the full minute.

If you call Mexico for 10 seconds, you will be charged for 1 whole minute (60 seconds minimum call charge, 60 second increments).

What are the billing increments?

Here are our billing increments by location:

  • USA and Canada: 6 second initial; 6 second increments.
  • Mexico: 60 seconds initial; 60 second increments.
  • Gambia: 60 seconds initial; 1 second increments.

Other countries: 1 seconds initial; 1 second increments.
