VoIP – Benefits of SIP Trunking over ISDN Services

SIP Trunking has many advantages over ISDN, they include: Lower cost of access The cost of the access component of SIP Trunking is typically significantly cheaper than the more costly ISDN services. Typically expensive individual ISDN line interfaces can be replaced by a single, (or multiple redundant) IP link (via either copper or fibre). This offers the added benefit of reducing capex and opex, as costs for an Ethernet line is dramatically lower than multiple ISDN lines, while offering significantly higher scalable bandwidth. Lower call rates SIP Trunking typically offers slightly lower call rates than ISDN services, on a case-by-case…

VoIP – Kazoo 2600HZ – troubleshooting – couch_compactor_fsm failure

,
couch_compactor_fsm failure if 2600hz plateform logs shows  couch_compactor_fsm failed to ping. solution: The compactor needs to know the cookie with which the BigCouch Erlang VM started because it needs to find out what ports BigCouch is listening on. Some folks run on non-standard ports, so the compactor will query the node directly to discover its configured ports. Failing to connect to BigCouch, compactor will use the ports configured in /etc/kazoo/config.ini to try compacting. Obviously this fails in most installs because most people are using HAProxy locally on 15984/15986 instead of 5984/5986. The cookie value in the system_config/whistle_couch doc should be set the…

Networking – Access Point

An access point is a device, such as a wireless router, that allows wireless devices to connect to a network. Most access points have built-in routers, while others must be connected to a router in order to provide network access. In either case, access points are typically hardwired to other devices, such as network switches or broadband modems. Access points can be found in many places, including houses, businesses, and public locations. In most houses, the access point is a wireless router, which is connected to a DSL or cable modem. However, some modems may include wireless capabilities, making the modem itself the access…
