French DID service disruption

We have been experiencing a service outage from one French network that has resulted in some French DID being unreachable. The network seem to be involved in a business or financial dispute beyond our control. For our part, we do appologise to any users experiencing inconvienience due to this outage.

French DID are available from an alternate network if purchased with the correct end user documentation; a scan of the end users passport and proof of a local address.

Example: Paris 20 channel DID available for €2.95 per month

Any users who would like to replace a French DID that is out of service should open a support ticket from with their account and one of our staff will be happy to assist.

SIP Trunking for PBX

Mydivert.com today announces the introduction of a SIP Trunking service available to all users.

SIP trunking means that we can send SIP call invites in the form DID@IP:port instead of EXTENSION@IP:port. This is especialy useful for users with multiple DID in their account and using Asterisk or PBX systems to route calls. The SIP trunk invite will enable the pbx to easily determine from which DID number an incoming calls has originated.

The sip trunk can be enabled via a support request and we hope to add a 'toggle' feature to the user account area soon.

what a great day ! - mydivert.com team

System Update - 5 min. service outage expected

We plan a system wide update this evening at around 8pm GMT. The planned update which is to fix a memory leak in our system backup proceedures will require a reboot of the sip1 cluster.

The service outage is not expected to exceed 5 mins. We thank all users for their understanding and appologise if any inconvienience or dropped calls are experienced.

Notes on Voice Fraud

An example of Voice Phishing fraud was exposed today involving a mydivert.com user.

Voice Phishing, also known as Vishing is the criminal use of telephone communications, most often using features facilitated by Voice over IP (VoIP), to gain access to private personal and financial information. While scams such as Email Phishing have been around for some time, Voice Phishing exploits the public's trust in landline telephone services, which have traditionally terminated in physical locations which are known to the telephone company, and associated with a bill-payer.

It should be understood by anyone using mydivert.com that although the technology provides flexability, and fantastic communication opportunites, it should not be seen as an anonymous service. At any time, a law enforcement agency may contact us requesting the user information for a purchased phone number, and we are obliged to forward these details. This policy is intended to protect the interests of the general public, mydivert.com users, and the VoIP business model.

In a case such as that exposed today, a potential fraudster should understand that the complete call history, IP history, and all other user data is passed to law enforcement agencies.

Configuration for Asterisk behind NAT

Following the rollout of our new sip cluster, and the introduction of Kamailio extension state management, we would like to publish the new Asterisk configuartion required to work with mydivert.com

This configuration example assumes that your Asterisk server is on a private IP address behind NAT. If your Asterisk is behind NAT it must be setup to work behind NAT, i.e it should send it's private IP address in the contact field. This way the mydivert.com server knows that the respective peer is behind NAT and it can send back the packet properly.

To configure Asterisk with mydivert.com please make the following replacements in the sip.conf example given below:

SIPUSERNAME = Your SIP account username
SIPPASSWORD = Your SIP account password
LOCAL-IP = Your asterisk LOCAL IP address (example: 192.168.1.0/255.255.255.0)
PUBLIC-IP = Your PUBLIC IP address (example: 200.43.215.194)

The configuration for Asterisk (sip.conf) should look like this :

[general]
disallow = all
allow = g729
allow = ulaw
allow = alaw
extenip = PUBLIC-IP
localnet = LOCAL-IP
context = default
nat = yes
domain = PUBLIC-IP

register => SIPUSERNAME:SIPPASSWORD@sip1.mydivert.com/SIPUSERNAME

[sip1.mydivert.com]
fromuser = SIPUSERNAME
username = SIPUSERNAME
authuser = SIPUSERNAME
insecure = very
dtmfmode = rfc2833
dtmf = rfc2833
disallow = all
allow = g729
allow = ulaw
allow = alaw
type = peer
host = sip1.mydivert.com
qualify = yes
nat = yes
context = default
canreinvite = yes
secret = SIPPASSWORD
