Checking SIP Messaging To/From the PBX

When debugging a SIP Trunking issue with a PBX it is extremely useful to be able to capture the SIP
messaging sent to/from it.

For the SL1100/SV8100 we recommend that you capture the SIP messaging sent over its connection
to the LAN/WAN using an appropriate mirroring device and a PC with wireshark installed.
