How to monitor sip provider responses?

Question

Telephony

Good day. Colleagues, please tell me, is there any technical possibility to configure monitoring using zabbix sip provider? It is also desirable to receive response codes from sip.

Answer 1

Do you want a permanent dump to parse the call-flow of the calls you need?
For this, an excellent option would be to use Homer sipcapture ( www.sipcapture.org github - https://github.com/sipcapture/homer )
By default, it has a dashboard in which you can see all SIP responses in the form of diagrams, a diagram of all users -agent (types of your terminal devices) and so on.
The main thing that Homer gives is that you can find the call you need by various parameters for a certain period and see its call-flow. Just like if you, for example, did a tcpdump and then looked at it in wireshark.
The result, by the way, can also be saved in pcap and then sent to someone, for example, to a telecom operator for analysis.
There is a powerful API that you can use outside the scope of Homer himself (outside of his GUI) and set up the alarms and thresholds you need)
The principle of operation is such that you turn sip traffic towards the homer on your PBX, and the homer parses everything and adds it to the mysql database .
The choice of how to wrap traffic depends on your equipment. Starting from banal mirroring, and not ending with the hep module in freeswitch, for example.
