Hola buenos días... soy nuevo en esta lista y estaba empezzando a meterme
con Kamailio, principalmente para configurarlo como SBC contra Teams, en
este caso.
Pero no consigo que me funcione. Si lanzo una llamadas desde el Teams, en

No consigo "recibir" nada.
Tengo generados los certificados y configurados en el tls.cfg del Kamailio:
[server:default]
method = TLSv1.2
verify_certificate = no
require_certificate = no
private_key = /etc/letsencrypt/ssl/cert.key
certificate = /etc/letsencrypt/ssl/cert.crt
ca_list = /etc/letsencrypt/ssl/ca.crt
Dentro del propio Kamailio tengo configurado para que devuelva un 200
KeepAlive al Teams cuando recibe un OPTIONS:
event_route[tm:local-request] {
if(is_method("OPTIONS") && $ru =~
"pstnhub.microsoft.com") {
append_hf("Contact: <sip: SBC_DNS
:5061;transport=tls>\r\n");
}
xlog("L_INFO", "Sent out tm request: $mb\n");
}
Y he midificado el record_route por este nuevo:
record_route_preset(" SBC_DNS :5061;transport=tls", " SBC_IP :5061");
He creado una dispatcher.list:
# setid(integer) destination(sip uri) flags (integer, optional),
priority(int,opt), attrs (str,optional)
1:1:sip:sip.pstnhub.microsoft.com;transport=tls 0 3 socket=tls: SBC_IP
:5061;ping_from= sip:SBC_DNS
2:1:sip:sip2.pstnhub.microsoft.com;transport=tls 0 2 socket=tls: SBC_IP
:5061;ping_from=sip: SBC_DNS
3:1:sip:sip3.pstnhub.microsoft.com;transport=tls 0 1 socket=tls: SBC_IP
:5061;ping_from=sip: SBC_DNS
4:1:sip:sip-all.pstnhub.microsoft.com;transport=tls 0 1 socket=tls: SBC_IP
:5061;ping_from=sip: SBC_DNS
Creo, que uno de los problemas es que no mando bien el OPTIONS hacia el
Teams, ya que este en su panel, me indica que el SBC está INACTIVO.
No se si podrías ayudarme a enderezar un poco esto....
Muchas gracias por todo..

Hola y bienvenido,
Aparentemente tienes que agregar un RR con un FQDN.
En la lista en inglés se ha hablado mucho de ese tema. Mira en los archives.
Un saludo

Hola y bienvenido,
Aparentemente tienes que agregar un RR con un FQDN.
En la lista en inglés se ha hablado mucho de ese tema. Mira en los
archives.
Un saludo

Hola buenos días... soy nuevo en esta lista y
estaba empezzando a meterme
con Kamailio, principalmente para configurarlo como SBC contra Teams, en
este caso.
Pero no consigo que me funcione. Si lanzo una llamadas desde el Teams, en
el Kamailio veo:

No consigo "recibir" nada.
Tengo generados los certificados y configurados en el tls.cfg del
Kamailio:
[server:default]
method = TLSv1.2
verify_certificate = no
require_certificate = no
private_key = /etc/letsencrypt/ssl/cert.key
certificate = /etc/letsencrypt/ssl/cert.crt
ca_list = /etc/letsencrypt/ssl/ca.crt
Dentro del propio Kamailio tengo configurado para que devuelva un 200
KeepAlive al Teams cuando recibe un OPTIONS:
event_route[tm:local-request] {
if(is_method("OPTIONS") && $ru =~
"pstnhub.microsoft.com") {
append_hf("Contact: <sip: SBC_DNS
:5061;transport=tls>\r\n");
}
xlog("L_INFO", "Sent out tm request: $mb\n");
}
Y he midificado el record_route por este nuevo:
record_route_preset(" SBC_DNS :5061;transport=tls", " SBC_IP
:5061");
He creado una dispatcher.list:
# setid(integer) destination(sip uri) flags (integer, optional),
priority(int,opt), attrs (str,optional)
1:1:sip:sip.pstnhub.microsoft.com;transport=tls 0 3 socket=tls: SBC_IP
:5061;ping_from= sip:SBC_DNS
2:1:sip:sip2.pstnhub.microsoft.com;transport=tls 0 2 socket=tls: SBC_IP
:5061;ping_from=sip: SBC_DNS
3:1:sip:sip3.pstnhub.microsoft.com;transport=tls 0 1 socket=tls: SBC_IP
:5061;ping_from=sip: SBC_DNS
4:1:sip:sip-all.pstnhub.microsoft.com;transport=tls 0 1 socket=tls:
SBC_IP :5061;ping_from=sip: SBC_DNS
Creo, que uno de los problemas es que no mando bien el OPTIONS hacia el
Teams, ya que este en su panel, me indica que el SBC está INACTIVO.
No se si podrías ayudarme a enderezar un poco esto....
Muchas gracias por todo..
Un saludo
