Port assignment

Hi all,

I am currently working with SIP protocol.

I have a node that is supposed to accept SIP invite. It should be listening on udp port 35060 but is not.

Code:
Every 2.0s: netstat -an| grep 5060                                                                                                                                     Thu Feb 26 13:45:36 2015

tcp        0	  0 192.168.2.106:35060         0.0.0.0:*                   LISTEN
tcp        0	  0 127.0.0.1:35060             0.0.0.0:*                   LISTEN
udp        0	  0 192.168.2.106:35060         0.0.0.0:*
udp        0	  0 127.0.0.1:35060             0.0.0.0:*

Because of this, when I run tcpdump , I get the following;

Code:
13:41:10.603075 IP pl-1 > 192.168.2.102: ICMP pl-1 udp port sip unreachable, length 556

How can I start listening on udp port rather than tcp ?

BR

NAME
repro - repro SIP proxy server SYNOPSIS
repro [OPTIONS...] DESCRIPTION
repro is an open-source, free SIP server. SIP is changing the way people communicate using the Internet. It is not only about making phone calls over the Net. The SIP protocol and its extensions defines the way of establishing, modifying and ending interactive sessions, no mat- ter if they are voice, video, IM or a combination of them. At the heart of SIP architecture, there are certain services which needs to be provided at some place of the network. repro provides SIP proxy, registrar, redirect, and identity services. These services are the foun- dation needed to run a SIP service. OPTIONS
-l, --log-type=cout|syslog|cerr Set where to send logging messages. The default cout sends the messages to standard output, cerr uses the standard error pipe. With syslog the messages are send to the system log using the logging facility local6. See syslogd(8) or syslog.conf(5) for more informa- tion. -v, --log-level=STACK|DEBUG|INFO|WARNING|ALERT Set the minimum level a logging message needs to have in order to by written. The severity rises from left to right in the above order. The default is to log messages with level INFO or above. -r, --record-route=sip:example.com Activate record routing. The argument is the URI used in the Record-Route header field. --udp=5060 Specify the port to use for the UDP transport. Set to 0 to turn UDP off. Defaults to port 5060. --tcp=5060 Specify the port to use for the TCP transport. Set to 0 to turn TCP off. Defaults to port 5060. -t, --tls-domain=example.com Act as a TLS server for specified domain. --tls=5061 Set the port to use for the TLS transport. Set to 0 to turn TLS off. Defaults to port 5061. --dtls=0 Set the port to use for the DTLS transport. Set to 0 to turn DTLS off which is the default. --enable-cert-server Run a cert server. -c, --cert-path=STRING Set the path for certificates. Defaults to ~/.sipCerts. --enable-v6 Enable IPv6. --disable-v4 Disable IPv4. --disable-auth Disable DIGEST challenges for certain SIP requests. --disable-web-auth Disable authentication for the web administration server. --disable-reg Disable the registrar. -i, --interfaces=sip:10.1.1.1:5065;transport=tls Specify interfaces to add transports to. Each transport is given as a SIP-URI with the IP address and port of the local interface as the hostport part and the transport protocol as a transport parameter. Several transports are separated by a comma. For example, to set up two transports, one for TLS and one for UDP use sip:192.168.1.200:5060;trans- port=tls,sip:192.168.1.200:5060;transport=udp -d, --domains=example.com,foo.com Specify the list of domains this proxy is authorative for separated by comma. -R, --route=sip:p1.example.com,sip:p2.example.com Specify a route set where all requests this proxy is authorative for are sent to. Using this option overides the routes set through the web interface. --reqChainName=STRING Name of request chain used for processing requests. Currently, the only chain available is default. --http=5080 Specify the port used by the HTTP server. Defaults to 5080. --recursive-redirect Enable to handle of 3xx responses in the proxy. --q-value Enable q-value processing. The q-value can be given in registrations and is used by the location server to order forwarding for mul- tiple registrations. Without this option a request is forked to all registrations. --q-value-behavior=FULL_SEQUENTIAL|EQUAL_Q_PARALLEL|FULL_PARALLEL Specify forking behavior if --q-value is given. With FULL_SEQUENTIAL one target is called after another in the order of their q values. Using EQUAL_Q_PARALLEL (the default), the request is sent in batches of all registrations with the same q value. The batches are again ordered by the q value. FULL_PARALLEL causes the request to be sent in parallel to all registrations. --q-value-cancel-btw-fork-groups If given, groups of parallel forks are canceled after the period specified by the --q-value-ms-before-cancel option if no response was received. --q-value-wait-for-terminate-btw-fork-groups If given, the proxy waits for groups of parallel forks to terminate before a new group is started. Otherwise, the next group is started once the waiting time has passed. --q-value-ms-between-fork-groups=INT Specify the number of milliseconds to wait for a response from a group of parallel forks before starting another group. --q-value-ms-before-cancel=INT Specify the number of milliseconds to wait before cancelling a group of parallel forks if the --q-value-cancel-btw-fork-groups option is given. -e, --enum-suffix=e164.arpa Specify enum suffix to search. -b, --allow-bad-reg Allow To tag in registrations. --timer-C=180 Specify the length of timer C in sec which specifies the time a proxy waits before generating a timeout response. Set to 0 or a neg- ative value to turn timer C of completely. --admin-password=STRING Set the web administrator password. Help options: -?, --help Show a help message. --usage Display brief usage message. --version Display the version information. SEE ALSO
