Logging Explanation

I'm trying to track down why some of our VVX 500 phones on 4.1.X are freezing when they get a large number of inbound BLF signaling packets.


I'm trying to turn up the logging but I want to make sure that I'm looking in the right places.


My hypothesis is that the unit cannot process the amount of packets it is receiving if several of the monitored lines receive BLF information at a single time (such as if a VVX 500 is monitoring a support queue via BLF and all of the members of that queue receive a call at the same time).


Per the admin guide I can make changes to the following modules

 These are the input filters into the internal memory-based log system. Possible values for xxx are acom, ares, app1, barcode, bluet, bdiag, brow, cap, cdp, cert, cfg, cipher, clink, clist, cmp, cmr, copy, curl, daa, dbs, dbuf, dhcpc, dis, dock, dot1x, dns, drvtbt, ec, efk, ethf, h323, hset, httpa, httpd, hw, ht, ib, key, ldap, lic, lldp, log, mb, mobil, net, niche, oaip, ocsp, osd, pcd, pdc, peer, pgui, pmt, pnetm, poll, pps, pres, pstn, ptt, push, pwrsv, rdisk, res, rtos, rtls, sec, sig, sip, slog, so, soem, srtp, sshc, ssps, style, sync, sys, ta, task, tls, trace, ttrs, usb, usbio, util, utilm, wdog, wifi, wlan, wmgr, and xmpp.


I couldn't find an explanation of what some of these components are.  Is that described elsewhere?  Perhaps in a technical document?


Thank you!

Re: Logging Explanation

Hello Eric_P,

welcome to the Polycom Community.

We usually do not disclose the meaning of the individual logging modules as these should only be changed if advised by our support team.


I would suggest you reply how many BLF's you are actually using and which are signaling an incoming call at the same time so we get a general idea.


The FAQ itself contains a general VoIP troubleshooting post here:
