Is my telephone system (PBX) compatible with SIP?

This really depends on the age of your PBX. Most modern telephone systems are hybrid, where they will work with SIP, and support legacy telephone lines like ISDN and analogue.

Even if your trusted PBX is old, don't rule it out - SIp is cheaper and may pay for your upgrade.

SIP provides very high call quality, but it is really important your LAN and Internet service is "voice ready".

The cabling should be good, your switches and firewall should be confiugred for voice prioritisation. Speak to our technical experts for a free consultation.
