These are OBi Service Access Codes. You dial a service access code before the number to manually route an outbound call to that service trunk. Their definition is arbitrary... they could be any number code... they just have to be supported by the dial plan, specifically the phone port digit map and outbound call route.
**70(Mli)|**8(Mbt)|**81(Mbt)|**82(Mbt2)
The above rules prepend a service access code to the number matched by the respective service trunk digit map... LINE, Bluetooth1, and Bluetooth2. **8 and **81 are redundant... you only need one code for Bluetooth1.
{(<**70:>(Mli)):li},{(<**82:>(Mbt2)):bt2},{(<**81:>(Mbt)):bt},{(<**8:>(Mbt)):bt}
The above rules match the prepended service access code to route the call to the respective service trunk, and also remove it from the number to be called. Again, **8 and **81 are redundant... you only need one code for Bluetooth1.
My OBi202 dial plan supports these service access codes as I've chose to define them:
**1 SP1 Service (ITSP SIP or Google XMPP trunk)
**2 SP2 Service (ITSP SIP or Google XMPP trunk)
**3 SP3 Service (ITSP SIP or Google XMPP trunk)
**4 SP4 Service (ITSP SIP or Google XMPP trunk)
**5 OBiTALK Provisioning registration. Use to dial a 4-digit authentication code when adding the device to the OBiTALK web portal. Registration transmits device information (model, serial number, etc.) and enables OBiTALK Provisioning to allow remote device configuration and firmware updates by Obihai. **5 does not require dial plan support and can be barred by the dial plan to prohibit use of OBiTALK Provisioning.
**6 Reserved
**6n VGn n=1,2,3,4,5,6,7,8 Voice Gateway (virtual trunk)
**7 Reserved
**7n TGn n=1,2,3,4 Trunk Group (virtual trunk)
**8 LI1 LINE Service (OBi110 or OBiLINE PSTN trunk)
**81 BT1 OBiBlueTooth Service (wireless trunk)
**82 BT2 OBiBlueTooth Service (wireless trunk)
**9 PP1 OBiTALK Service (peer-to-peer trunk)
Ideally, the dial plan should not require using service access codes to manually route calls on a regular basis... the desired routing should be automatic, imo.
