Symphony Meetings - on-prem recording SIP Bridge FAQs



Where are the SIP Bridge logs?

The logs for the SIP Bridge are located in the /logs folder. In the event of any issues with recording, the support team will usually request the following 2 log files:

  • sip-bridge.log.
  • smb.log.

Is whitelisting part of the network requirements?

Whitelisting is required between the Recording Bridge and the Recorder. The user must ensure that the following traffic between the SIP Bridge and the Recorder is whitelisted:

  • tcp 5060-5061 (SIP traffic).
  • udp 10000-20000 (RTP media).

The user can change the UDP ports above to suit their internal network infrastructure. This setting can be changed in the file:

  • smb.udpPortRangeLow=10000.
  • smb.udpPortRangeHigh=20000.

Additionally, the user can change the default SIP port by changing:

  • #recording.sip.port=5061.

10000-20000 is the default range if no setting is applied.

How do I configure a proxy server?

The Recording Bridge supports access through a Proxy server. This can be configured in the file:

  • ### Proxy settings (OPTIONAL) ###.
  • #sipbridge.proxy.port=-1.
  • #sipbridge.proxy.user=fixme.
  • #sipbridge.proxy.password=fixme.
