If you mean, if there is another way appart from doing a lookup() call ... that depends on what you whant to do ... 'kamctl ul show' it's really a RPC call to the registar module, but if you store your location information on any DB backend (redis, mysql, etc.) you could use other modules like sqlops, redis, etc. to do searchs and manipulations.

Hello, There are different functions in the registrar module, check them out: https://kamailio.org/docs/modules/devel/modules/registrar.html#idm576 reg_fetch_contacts(..) might be something you could use.

Hello, maybe is better I explain what I'd like to achieve: I have two Kamailio using DMQ and DMQ_USRLOC modules so each REGISTER is replicate on each Kamailio. I'm using DNS weight to distribute the REGISTERs between the 2 Kamailios. The only difference I have seen in the location data, with *kamctl ul show* command, is the Kamailio receives REGISTER have socket parameter with transport, ip, y port like udp:1.2.3.4:5060 where 1.2.3.4 is Kamailio public IP; the other Kamailio have this field empty. When a call arrive to one Kamailio, querying the Socket field I can known if I have to send the INVITE locally or forward the INVITE to second Kamailio. I don't know if there is other way to achieve this goal. I think PATH protocol not apply here because If I reply the REGISTER to the second Kamailio adding path header, I don't need DMQ_USRLOC. The idea is to take advantage of using these DMQ related modules. Regards --- I'm SoCIaL, MayBe El 29/07/2021 a las 5:16 p. m., Henning Westerholt escribió:

Hello, have you looked to the reg_fetch_contact as already pointed out? Then you can access e.g. the socket with the $ulc PV, see the end of the registrar docs for an example.

Hi, just quickly looked in the registrar code, it uses the standard usrloc functions to get data from memory or database. Maybe just give it a try, I think it should work also in in-memory/dmq mode.

Works! I can access location data presents only in the memory. Now, next step is using $(ulc(contacto=>socket)) to decide which kamailio have to process the call. Thank you --- I'm SoCIaL, MayBe El 30/07/2021 a las 11:51 a. m., Henning Westerholt escribió:

LIMITATIONS: * works only with a device for user. If a user registered from two o more devices I don't know how achieve the same behavior * works with Two Kamailio due to rewritehost function... * maybe the routing can be better Regards --- I'm SoCIaL, MayBe El 31/07/2021 a las 5:23 a. m., Henning Westerholt escribió:

Great, thanks for the confirmation.

I can access location data presents only in the memory. Now, next step is using $(ulc(contacto=>socket)) to decide which Kamailio have to process the call.

Maybe just give it a try, I think it should work also in in-memory/dmq mode.

Then you can access e.g. the socket with the $ulc PV, see the end of the registrar docs for an example.

I'm using DNS weight to distribute the REGISTERs between the 2 Kamailios. The only difference I have seen in the location data, with *kamctl ul show* command, is the Kamailio receives REGISTER have socket parameter with transport, ip, y port like udp:1.2.3.4:5060 where 1.2.3.4 is Kamailio public IP; the other Kamailio have this field empty. When a call arrive to one Kamailio, querying the Socket field I can known if I have to send the INVITE locally or forward the INVITE to second Kamailio. I don't know if there is other way to achieve this goal. I think PATH protocol not apply here because If I reply the REGISTER to the second Kamailio adding path header, I don't need DMQ_USRLOC. The idea is to take advantage of using these DMQ related modules.
