Parameter –
sip local port
Aastra Web UI: Advanced Settings->Global SIP->
Advanced SIP Settings
Configuration Files aastra.cfg, <mac>.cfg
Description Specifies the local source port (UDP/TCP) from which the phone sends
SIP messages.
Format Numeric
Default Value 5060
Range Greater than 1024 and less than 65535
Notes :
1. It is recommended that you avoid the conflict RTP port range in case
of a UDP transport.
2. By default, the IP phones use symmetric UDP signaling for outgoing
UDP SIP messages. When symmetric UDP is enabled, the IP phone
generates and listens for UDP messages using port 5060.If symmetric
UDP signaling is disabled, the phone sends from random ports but it
listens on the configured SIP local port.
Example sip local port: 5060
