Hi List, I have the following error message in the console: 2012-06-26 11:29:33.399845 [ERR] switch_ivr.c:1414 Can't re-establsh media on sofia/INSIDE/1000@10.10.10.10:5060 My dialplan is the following: - set bypass_media = true (I don't want to process RTP on freeswitch) - bridge the call - if bridge is unsuccessful, I execute a perl script The Perl script catch the sip_error_code that is returned and I play an annoucement message depending on the SIP error. In the perl script I do the following: - set bypass_media = false - use pre_answer to trigger a SIP 183 cause I don't want the call to be billed - playback error message - hangup with error code Everything is working fine, I have a SIP 183, the message is played and bill_duration = 0; but I have the error message above in console. If I use answer, instead of pre_answer, the message is played and the error message disapear but bill_duration is not null. I tried to use uuid_media in my perl script but this is not working. I got an error message, I assume this is because uuid_media should be used when call is bridged. If somebody as an idea to share :p regards, Rod.
