Tietong's fixed phone number and mobile phone number are used for binding. The caller of such users is the fixed phone number, and both numbers can be used for incoming calls (called). The specific method is to regularly bind the mobile number of the wireless landline at home with a fixed number, such as a mobile phone.

18802995678, and the fixed-line number is 86 135678.

The last four are the same.

1. Intra-group call processing

1) expiratory in the group

The main call of business communication is to dial the short number of mobile phone or fixed line, and the mobile GMSC/SSP triggers the integrated VPMN service.

2) Incoming calls within the group

Within the mobile network: the mobile phone dials the short number of the business phone, triggers the integrated VPMN service through the mobile GMSC/SSP, and translates the long number of the business phone (1 1 mobile phone number).

In CTT network: CTT calls the short number of business phone, bypasses the mobile network through dedicated free relay EJ, and triggers the integrated VPMN service through mobile GMSC/SSP to translate the long number of business phone (1 1 mobile phone number).

2. Outside the group call processing

1) group expiratory.

The calling number is converted into a fixed-line number by the connected exchange (for example, the first 7 digits are replaced by 86 13 digits, and the called party displays the 8-digit fixed-line caller). The integrated VPMN service is not triggered, and all calls (local and long distance) are detoured to Tietong through special free relay EJ, and Tietong realizes traffic diversion and charging.

2) Incoming calls from outside the group

Incoming calls are resolved in the following ways:

(1) If you dial the mobile phone number, connect it in the original way.

(2) Dial the fixed-line number of Tietong and enter from Tietong. The first four digits of the called number will be replaced by 180299 by Tietong Gateway, which will be converted into a mobile phone number and sent to the mobile gateway.
