"ABTO SIP SDK has provided Xenex with a robust SIP toolkit that is enabling us to provide extra information to our staff that out VoIP PBX is not able to. It is very easy to use, something that can't be said for other toolkits, and is giving us lots of other ideas on how to use it to benefit both our staff and our customers. Thanks ABTO SIP SDK for your Internet phone sdk!"
