Sip Trunks

Coms delivers carrier class voice calls over SIP Trunks

SIP Trunks allow businesses to retain their existing telecoms equipment, whilst gaining the additional uses and benefits of VoIP Telephony.

Typically, SIP Trunks enable costly standard or ISDN (BRI or PRI) telephone lines to be replaced by a single IP connection. SIP Trunks can be linked directly to an onsite IP-PBX or to a traditional PBX using a Gateway. Outgoing calls are then routed through the PBX and out via the SIP Trunk, rather than using costly traditional phone lines.

Coms’s carrier class platform, ComsX, is a high availablility and fully redundant carrier class service.  
 
 
 

Coms SIP Trunks deliver the following key benefits

• The ability to reduce analogue or ISDN lines, because up to 100 simultaneous calls can be made per Coms SIP Trunk account.
• Reduced Call costs, with Coms discount call rates.
• Call Quality is excellent, our “single Hop” service is VoIP to ComsX, and then traditional TDM to the called party.
• Calls are terminated via multiple Tier-1 routes, delivering excellent call quality and redundancy using dynamic route selection.
• Hot Billing with online billing and CDR’s (Call Data Records).
• Calls are billed in one second segments.
• Our customers are not tied into long term contracts.

Additional QoS is available when bundled with Coms IP Connect Broadband
