Hello; i found the problem i hope i can explain the problem to get solution. when first usage of load_gws() and next_gw() functions , next_gw() fills all uri avps to ru_AVPs from gws tables. if it goes to failure route or route again , it can re use ru_AVPs in next_gw(). so if recall the load_gws() again for choose new route , it uses old uri avps in next_gw() function , it is totally incorrect. if there is flag or parameter to define gws are reloaded , it can null to ru_AVPs to correct gws informations. i couldn't find why fromuri appending itself. searching about it. Thanks. -- View this message in context: http://sip-router.1086192.n5.nabble.com/LCR-module-re-load-gws-uri-errors-t… Sent from the Users mailing list archive at Nabble.com.

does it work if you destroy (e.g. using avp_delete("$avp(x)/g")) gw_uri_avp and ruri_user_avp before the second load_gws() call?

i couldn't find why fromuri appending itself. searching about it.

if i remember correctly, lcr functions do not modify from uri. -- juha

Hey; Thanks for reply. before load_gws , setting ruri_user_avp to null solves request uri problems. -- View this message in context: http://sip-router.1086192.n5.nabble.com/LCR-module-re-load-gws-uri-errors-t… Sent from the Users mailing list archive at Nabble.com.

load_gws() tries to delete possibly existing avp values by this statement: delete_avp(gw_uri_avp_type|AVP_VAL_STR, gw_uri_avp); obviously there is something wrong with if the avp needs to be deleted by the script. i'll try at some point try to figure out how to delete an avp based on its name. -- juha

in load_gws function there is a delete_avp for gw_uri_avp as you mentioned . but in my view it needs a delete_avp for ruri_user_avp. Because it is reloading gws for different route.

I added deletion of possible old ruri_user_avp value when next_gw() is called first time after load_gws(). It is currently in master branch only, but I can commit also to 4.3 branch if this fixes the issue. -- Juha
