This might be better suited to doing in a SIP proxy at the edge, like OpenSIPS. R-URI formatting is complicated. The # might be a URI fragment and be discarded by some UAs or might be illegal and rejected. It might be worth it to try to avoid such URIs in the first place. -Michael From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Vladislav Ivanov Sent: Friday, 10 June, 2016 2:17 To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Subject: [Freeswitch-users] Safe SIP URI Formatting Hello, Is it possible to somehow alter the logic of Safe URI Formating to not transform '#' sign to '%23'? Maybe I can somehow escape the hash sign to not transform? There is some equipments that cant do back-formating and reject calls with "%23" signs with them. Best Regards
