Hello,
I build three kamailioes, one acts as a pass-through proxy as well as load-balancing, the
two registrars.
The kamailio_1 decides to which registrar the REGISTER should forward by a dispatcher
based on db_text.
----->kamailio_2(IP2, registrar)
SoftPhone--->kamailio_1(IP1, pass-through proxy)--|
|
----->kamailio_3(IP3, registrar)
|
dispatcher(db_text)
I expect the kamailio_1 forward the REGISTERs to kamailio_2/kamailio_3, and
kamailio_2/kamailio_3 respond with 200 OK. But in fact, the registrars send the REGISTER
back to kamailio_1.
I think the reason is that the host part of Request-URI in REGISTER from SoftPhone is IP1,
and kamailio_1 does not rewrite it as a pass-through proxy, so kamailio_2/kamailio_3 will
find the host in Request-URI is not mine, thus route the REGISTER back to kamailio_1
according Request-URI.
The setting of SoftPhone cannot be changed, so is it possible to :
1) replace host part of Request-URI in the REGISTERs with the result of dispatcher in
kamailio_1 , or
2) force kamailio_2/kamailio_3 to respond rather than forward?
Thanks!
