Business voice communications
VoIP for the way your business works.
From an initial SIP connection to changes in live operation, SpeedNetwork is your point of contact for professional voice communication and the technical questions around it.
For businesses that depend on voice communication
Connect your phone system
Connect SIP-based systems to an appropriate voice service. Confirm interoperability, authentication and number use first.
Plan contact centre telephony
Consider traffic profile, concurrent calls and dialling behaviour together, with or without Dial24.
Integrate a platform
Define interconnection points and call direction for your applications and BYOC projects.
Getting started as a prospective customer
Describe your requirements
Which phone system or platform do you use? Which countries, numbers and call volumes matter?
Agree the connection
Review SIP parameters, codecs, authentication, number signalling and capacity requirements.
Test deliberately
Use agreed test cases to check incoming and outgoing calls, audio and failure behaviour.
Prepare for operation
Document responsibilities, contact routes and the agreed service scope.
Already a VoIP customer?
For changes and technical enquiries, use your agreed contact route or email info@speednetwork.de. The guidance below helps us identify what your enquiry relates to.
Change or extension
Identify your account, affected service and requested change. Number and capacity changes require technical and contractual review.
Technical issue
Include time and time zone, call direction, observed behaviour and, where available, a SIP error code or call ID. Agree a secure route before sending sensitive traces.
Numbers & changes of provider
Identify the numbers involved and the planned date. Number use, supporting documents and any porting requirements are checked separately.
Do not send passwords. This website is not a service-status monitor or an emergency channel. Response times and support availability depend on your agreement.
Technical detail, not blanket promises
Country coverage, number availability, encryption, features and commercial terms depend on the specific service and infrastructure involved. We clarify these points before making a commitment.
