SIP Trunking for Business

It's one of the best switches your business can make. SIP Trunking is a better solution.

Flexibility with phone numbers

SIP trunking enables you to move office and keep the same geographic number without any ongoing call forwarding costs or those associated with producing new company stationery.

Business continuity

If your office has to be temporarily relocated in an emergency, this can be achieved quickly and cost-effectively with SIP trunking to keep your business working.

Line rationalisation

For businesses with multiple sites, SIP trunking provides the opportunity for line rationalisation and reduces the number of PBXs you need to maintain - while retaining full control of the numbers associated with your business.

Save money

IP connectivity costs less than ISDN with lower call costs, free internal calls between extensions and offices and lower line rental costs for multi-sites. Also, no expensive call forwarding costs are required should you relocate or need to divert calls in the event of a disaster.


SIP trunking provides a phone service that will cope with any situation and give you business-grade resilience for your phone system. Whether you need to keep your business running in a disaster or emergency or you need to load balance your calls between sites during peak hours, SIP trunking delivers.

Compatible with others

Welltel SIP trunks are integration tested and approved to interoperate with a number of other systems and PBXs. We are compatible with NEC, Avaya, Shoretel, 3com, Samsung, Aastra, Linksys, Cisco, Asterisk, Panasonic and many other leading phone system providers.
