Information Systems:ThinkTel SIP Trunk
Overview
ThinkTel is our primary phone service (SIP trunk) provider. We have two SIP trunks, one is a reservation trunk for parking DIDs that we do not use.
| Trunk | Pilot number | Number of channels | Notes |
|---|---|---|---|
| Main | 778-732-4693 | 10 | Main trunk. Max number of channels is 15 (9 committed, 6 burstable). |
| Reservation trunk | 778-732-4650 | - | About 65 of our ~102 DIDs associated with this trunk. Not usable for calls. |
uControl Web Administration
uControl is ThinkTel's user portal for technical and billing administration. Most components of the SIP trunk service can be modified here, including adding/removing channels and DIDs.
Configuration
SIP Trunk Bindings
A SIP Binding is required to define a connection between a ThinkTel SIP trunk and a PBX i.e. it specifies where ThinkTel will route the calls to. Because 3CX is reachable via our Telus Business Fibre connection as well as our Shaw Business Internet (cable) cable, two bindings are needed. The settings for the main connection are as follows (Shaw to be added later):
Contact End Point: 207.102.139.100:5060 Proxy End Point: 208.68.17.52:5060 SIP Domain Name: edm.trk.tprm.ca Enabled: True Maximum Channels: 15 Channel commit: 9
SureCall
If ThinkTel cannot reach our PBX via any of the SIP bindings, a feature called Surecall (if enabled) forwards the calls to another number.
Reservation Trunk (inactive DIDs)
ThinkTel offers "DID parking", which allows us to save on the v911 fee per DID on DIDs that are not actively used. This is done by assigning the numbers to a reservation trunk, which in essence is another SIP trunk altogether.
