Ericsson to divest its enterprise PBX solutions to Aastra Technologies - Ericsson Ericsson has a strategic focus on telecommunication operators and service providers, hence considers its enterprise PBX solutions business to be outside its core focus. In addition, the enterprise communications industry is becoming increasingly global and is clearly gravitating toward consolidation. Therefore, Ericsson believes that the enterprise PBX solutions will add significant competence and value to Aastra Technologies, adding leading products and a significant customer base for PBX solutions. This will also be a positive step for Ericsson's enterprise customers, partners and employees, combining Ericsson's and Aastra Technologies' leading product portfolios.

Aastra: Aastra Technologies to acquire Ericsson’s As the enterprise communication market continues its evolution to VoIP, Aastra believes the acquisition of Ericsson’s Enterprise Communication Business will provide it with the increased scale to be a leading player in Western Europe while creating an important footprint for Aastra in a number of key markets across Eastern Europe, Asia, Australia, the Middle East, Africa and South America.

Telephone ringing circuits What is ring signal ? The telephone company sends a ringing signal which is an AC waveform. Although the common frequency used in the United States is 20 HZ and in Europe is typically 25 Hz, it can be any frequency between 15 and 68 Hz. Most of the world uses frequencies between 20 and 40 Hz. The voltage at the subscribers end depends upon loop length and number of ringers attached to the line; it could be between 40 and 150 Volts. The ringing cadence - the timing of ringing to pause - varies from telephone company to company. The usual arrangement is to feed the 75 V a.c. ringing current (backed by earth) down one wire of the phone line. On the other wire is placed a slugged relay (or equivalent) which is backed by -48V d.c. When you pick up the phone , the relay operates to the loop d.c. current and trips the ringing current. It also triggers a further device to put the transmission bridge in circuit to enable speech to take place, t...

Cisco IOS Voice Troubleshooting and Monitoring -- FXS Interfaces - DocWiki Ring Voltage Problems Voltage problems can cause three types of problems: Answering and Call Initiation Problems with Automated Telephony Devices Ringing Problems FXS Ring Failure in the United Kingdom Certain automated devices, such as fax machines, answer machines, multiline phones and voice mail systems, look at the line voltage in order to deduce if the line is busy or idle. If another device is off hook, then the line voltage drops, and the automated system does not answer or initiate a call. If the threshold being used is close to -24 V or higher, this can cause the device not to work as expected. Certain phones might not ring when the default ring voltage and ring frequency are applied from the Cisco FXS interface. For situations where the line voltage is not high enough, a ring booster can be installed between the interface card and the network.

Understanding Why Telephones in the United Kingdom Connected to Cisco FXS Interfaces May Fail to Ring [Telephony Signaling] - Cisco Systems n the UK certain British Approval Board for Telecommunications (BABT) telephones fail to ring when they are connected to FXS ports on Cisco voice-enabled routers and switches. Outgoing calls can be made and voice communication in both directions can be established, however with incoming calls, the telephones will not ring. These telephones functioned correctly before being connected to the FXS ports.

Asterisk - Intermittent beep with linksys SPA 3102, PAP2, DTMF sounds heard during conversation Asterisk - Intermittent beep with linksys SPA 3102, PAP2, DTMF sounds heard during conversation We had users reporting hearing DTMF sounds during a conversation. We have solved the problem by switching DTMF mode to INBAND in the SPA 3102 config, in the PAP2 config and into Asterisk/FreePBX configuration. 1) In your SPA-3102 html interface, go to /admin/voice/advanced, Line 1 and PSTN Line and set DTMF Tx Method: INBAND in both places. 2) Since we have an asterisk extension mapped to the SPA-3102 Line1, we also went into FreePBX and set the dtmfmode to: "inband" for that extension. (was previously set to SIP-INFO) 3) We also have a SIP trunk in asterisk mapped to the SPA-3102 PSTN line.
