What ports on the U1960 can be mapped to the public network for external users to register with the U1960

152

The default registration port for SIP numbers is 5060, and the available RTP port ranges from 10000 to 65535 (the start RTP port can be changed using the 317 software parameter by running the config rtp portstart command).
It is recommended that you download the U1900 communication matrix and modify or map related ports as required.

Other related questions:

Can the U1900 be connected to the SIP trunk though the public network?

The U1900 cannot be connected to the SIP trunk though the public network because this involves the network address translation (NAT) issue. It is not allowed to use the SIP ALG function of the firewall because this function has not been tested under the lab environment. If the U1900 must be connected to the SIP trunk through the public network, use the session border controller (SBC).

Must the account registered on the IAD1224 connected to the U1960 match the corresponding slot and port of the IAD?

When a user registers an SIP number on the IAD, the port and slot to which the number corresponds depend on the number planning for the phone line of the port. When a specific number is planned for a workstation (room), find out the slot and port of the IAD to which the phone line of the workstation (room) is connected. Then register the number.

Network port modes of the U1960

The control boards of the U1911/U1960/U1980/U1981 support three network port modes: single-network-port mode, dual-network-port mode, and triple-network port mode. In different network port modes, each network port processes different data streams. Network port 3 is not used currently. For details, see the U1900 product documentation.

How can U1960 users join a conference by individual dialing-in

Users need to first obtain the conference access code, conference ID, and conference password from the conference initiator. Then, they can dial the conference access code and enter the conference ID and password as prompted to join the conference.

How do U1960 users retrieve voice massages?

U1900 users can directly dial the access code for retrieving messages and retrieve messages following the voice prompts.
