I will fix asterisk freepbx sip trunk and voip call issues
About this Gig
I fix Asterisk, FreePBX and SIP trunk problems such as failed calls, one-way audio, registration errors and broken inbound or outbound routing.
I work on business VoIP systems and focus on the actual fault instead of turning every job into a larger rebuild.
I can help with:
SIP registration and authentication
inbound and outbound routing
one-way or missing audio
IVR, queues and extensions
call drops and intermittent failures
NAT and firewall interaction
configuration and log review
3CX or carrier integrations via a custom offer
You receive:
a clear diagnosis
the agreed work within the selected package
tested call behavior
short, practical handover notes
Please message me before ordering if the job involves multiple sites, a migration, a custom carrier setup or a production system with a tight maintenance window. That way we can define the scope properly before anything is changed.
Support is available in English or German.

FAQ
What access do you need?
That depends on the issue. We can start with logs, screenshots and a clear call example. If remote access is needed, we agree on the method after the order. Please do not paste passwords into the requirements form.
Can you work on a live production system?
Yes, after we agree on the maintenance window, backup and rollback approach. Please message me before ordering if downtime must be avoided or several locations are involved.
Do you also support 3CX or carrier integrations?
Yes, for defined SIP, 3CX and carrier integration work. Because these jobs vary, please message me first and I will suggest the right package or a custom offer.
Can you guarantee the issue will be fixed?
The package covers the stated hours and scope, not an unlimited result guarantee. You will receive a clear diagnosis, the work completed within scope and practical next steps if a third party or larger rebuild is needed.
Do you provide support in German?
Yes. Communication and handover notes are available in English or German.
