Hello All,
I have an integration with Kamailio and FusionPBX (Freeswitch) working
great but I been trying to troubleshoot a BLF issue with Kamailio where the
BLF seems to only work when Kamailio is on a Public IP rather than behind
NAT. The BLF works fine when we register directly with Freeswitch either
on a Public IP or behind NAT.
Both Kamailio and FusionPBX (Freeswitch) are behind pfSense firewall on
private IPs and registrations, Inbound and Outbound Calls etc are working
fine. Just this BLF issue giving me some grief. The phone in question is
a Yealink T20.
I made some SIP Traces and I noticed the following:
In the FS Message Header I see we have the SUBSCRIBE:

Hello,
the phone has to send SUBSCRIBE for blf, kamailio cannot do anything for
that. Maybe the phone is misconfigured. Do you have any logs from the
phone saying what it tries and what doesn't work?
Cheers,
Daniel

Hi Daniel,
The phone is sending the SUBSCRIBE for BLF and I have included a more
detailed trace.
Just for clarity sake, the problem I am having is that the assigned BLF
line doesn't light up.

Hello,
the phone has to send SUBSCRIBE for blf, kamailio cannot do anything for
that. Maybe the phone is misconfigured. Do you have any logs from the phone
saying what it tries and what doesn't work?

Hello All,
I have an integration with Kamailio and FusionPBX (Freeswitch) working
great but I been trying to troubleshoot a BLF issue with Kamailio where the
BLF seems to only work when Kamailio is on a Public IP rather than behind
NAT. The BLF works fine when we register directly with Freeswitch either
on a Public IP or behind NAT.
Both Kamailio and FusionPBX (Freeswitch) are behind pfSense firewall on
private IPs and registrations, Inbound and Outbound Calls etc are working
fine. Just this BLF issue giving me some grief. The phone in question is
a Yealink T20.
I made some SIP Traces and I noticed the following:
In the FS Message Header I see we have the SUBSCRIBE:

Hello,
301 doesn't advertise support for SUBSCRIBE and you try to forward such
method to it via location service. Look at registrar module docs and
disable method filtering, then subscribe should be sent out.
Cheers,
Daniel

Hi Daniel,
The phone is sending the SUBSCRIBE for BLF and I have included a more
detailed trace.
Just for clarity sake, the problem I am having is that the assigned
BLF line doesn't light up.

Hello,
the phone has to send SUBSCRIBE for blf, kamailio cannot do
anything for that. Maybe the phone is misconfigured. Do you have
any logs from the phone saying what it tries and what doesn't work?
Cheers,
Daniel

Hello All,
I have an integration with Kamailio and FusionPBX (Freeswitch)
working great but I been trying to troubleshoot a BLF issue with
Kamailio where the BLF seems to only work when Kamailio is on a
Public IP rather than behind NAT. The BLF works fine when we
register directly with Freeswitch either on a Public IP or behind
NAT.
Both Kamailio and FusionPBX (Freeswitch) are behind pfSense
firewall on private IPs and registrations, Inbound and Outbound
Calls etc are working fine. Just this BLF issue giving me some
grief. The phone in question is a Yealink T20.
I made some SIP Traces and I noticed the following:
In the FS Message Header I see we have the SUBSCRIBE:
