[SR-Users] uac_replace_from() and multiple branches

v5.2.3 of Kamailio. Serial forking is used to route calls to a multiple destinations as described in documentation for the TM module. Also using the DIALOG module - my script calls dlg_manage() before loading the serialised branches. I need to be able to substitute the username part of the From header and have been trying this with calls to uac_replace_from(). modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) There is no problem if all branches use one substituted From username, in which case my script calls uac_replace_from() in the main route. uac_replace_from("sip:" + $avp(route:src) + "@" + $fd); However, I may need to substitute a different value for each branch. Can this be done? I tried moving the call to uac_replace_from() into the branch route, but then I get an error when the final BYE is received: ERROR: uac [replace.c:281]: replace_uri(): decline FROM replacing in sequential request in auto mode (has TO tag) Is there a simple solution to this please? Hoping I can still use UAC auto restore mode because manual restore looks quite tedious/complex. Thanks. John Quick Smartvox Limited www.smartvox.co.uk
