Appendix E: Ascom i62 Ports

This appendix lists the TCP and UDP ports the handset listens on for incoming and outgoing
traffic. The information applies to firewalls, network devices, traffic shaping and third-party
product settings.
E.1 Signaling
E.1.1 SIP
The following port numbers are configurable through the PDM:
Application
UDP
TCP
TLS
E.1.2 H.323
Application
Gateway interfaces
Gateway interfaces, additional ports
E.2 Voice Traffic
For a voice connection, one RTP and one RTCP port are used. A call therefore uses two free
UDP ports selected from the RTP port range. The RTP port range is, by default, from 16384
to 32767. The port range is then used for H.323 and SIP calls.
