As a followup to my earlier message, I have also found that the pua table in my database is empty. Since I have pua activated and db_mode set to 2 (see config file below), I don't understand why I am not getting any entries in the pua table. And I wonder if this is related to the lack of notify's that I am seeing. Anybody?

We have tried all of your suggestions, but still not getting any light changes on the watcher.
The basic problem seems to be that the watched phone sends PUBLISH packets to the server, but the server does not send NOTIFY packets to the watcher phone.
We are seeing the following error in the logs every time the watched phone changes status:

DEBUG: presence [notify.c:1263]: publ_notify(): Could not find subs_dialog

We are running Kam 4.4.2

If anybody has any ideas what could be causing this, let me know.


Thanks in advance, Bill

This works fine. On the T41P I went to the DSSKey tab, configured Line Key4 as follows:

:: Type: BLF

:: Line 1

The value has 2 parts:

:: The phone number of the user to whom we are subscribing
:: The domain name that this user registers to. This bit is important in Kamailio. If you want BLF, all UAs need to use the same domain name

The line should be the line that is registered to the server you are subscribing too.

It should be noted that we are running a forked/patched version of Kamailio 4.3.4. The relevant git commits are:

:: 2e99fe0
:: 56f3e25
:: b2843e5
:: a9ece27
:: d97f47c
:: fb2ede3
:: feef158
:: 19fce63
:: b5f9fb1

I think all but the last 4 are in 4.4. The last 4 are on Github as pull requests into master. Daniel is going to review when he has time... but we've been running in production for around a week now with no issues.

We're also running a fairly carefully crafted config to work around a number of other bugs with pua/presence which we didn't have the time to find a proper code solution for. Config is below:

phil@ua-proxy-dev:~$ grep 'pua\|presence' /etc/kamailio/kamailio.cfg
loadmodule "presence.so"
loadmodule "presence_xml.so"
loadmodule "presence_mwi.so"
loadmodule "presence_dialoginfo.so"
loadmodule "pua.so"
loadmodule "pua_dialoginfo.so"
# ----- presence params -----
modparam("presence", "db_url", DBURL)
modparam("presence", "db_update_period", 20)
modparam("presence", "clean_period", 60)
modparam("presence", "local_log_facility", "LOG_LOCAL3")
modparam("presence", "max_expires", 14430) # PortaOne max call time (4 hours) plus a little
# ----- presence_xml params -----
modparam("presence_xml", "db_url", DBURL)
modparam("presence_xml", "force_active", 1)
# ----- pua params -----
modparam("pua", "db_url", DBURL)
modparam("pua", "db_mode", 0) # Memory only. Required due to the "multiple states for a single dialog" bug
modparam("pua", "update_period", 20)
modparam("pua", "outbound_proxy", MY_SIP_URL)
# ----- pua_dialoginfo params -----
modparam("pua_dialoginfo", "send_publish_flag", FLT_DLGINFO)
modparam("pua_dialoginfo", "override_lifetime", 14420) # PortaOne max call time (4 hours) plus a little
modparam("pua_dialoginfo", "callee_trying", 1) # Implemented by Phil - submitted upstream to v4.4

pua db_mode can probably be changed to 2 following the recent fixes that are awaiting pull request review. We haven't tested this yet, though.

I have asked this question before, but never really got an answer:

Has anybody been able to get BLF working with Yealink phones.
