Migrating to Yellowgrid Advanced SIP Trunks
Our Advanced SIP Trunks are credential based and further secured by FQDN. This significantly improves any fail over scenarios as there is not requirement to update a SIP Trunk IP address. Further details can be found here.
The cost of our Standard SIP Trunks are the same as the cost of our Advanced SIP Trunks.
For those wishing to migrate from Standard to Advanced, it is a similar process to migrating to a new SIP Trunk provider, albeit without the number porting headache.
The following guidance should be followed to migrate from our Standard SIP Trunks to our Advanced SIP Trunks:
- Email your request to porting@yellowgrid.co.uk, providing the existing SIP ID and requesting that all numbers be migrated to our Advanced SIP Trunk services.
2. You will be supplied with new Advanced SIP Trunk details to add into 3CX Voice & Chat.
3. Change all Outbound Rules that use the Standard SIP Trunk to use the NEW Advanced SIP Trunk
4. Change all Emergency Numbers that use the Standard SIP Trunk to use the NEW Advanced SIP Trunk
5. Test Outbound Calls
6. Add all DDIs to the NEW Advanced SIP Trunk
7. Check for any CID rules. Export CID rules and import after changing the trunk ID
8. Audit and DOCUMENT all inbound routing for all DDIs (SIP trunk routing, Call Handling DDI assignment, Extension DDI assignment)
Then at a scheduled time, ask us to migrate the numbers (This can take up to 10 minutes and must be done between 9am – 5pm) whilst you complete the following tasks:
1. Delete existing SIP Trunk
2. Recreate all inbound routing by assigning the documented DDIs to Call Handling Groups, Extensions and ensure that the NEW Advanced Trunk routes as the previous Standard SIP Trunk
