I am trouble finding a configuration that works for ChanIsAvail and SIP. My two providers are Voxee and Teliax. I have these lines in a macro exten => s,n,ChanIsAvail(SIP/teliax&SIP/voxee) exten => s,n,Cut(CH=AVAILCHAN,-,1) exten => s,n,NoOp(AVAILCHAN= ${CH}) ; Dial the available Channel exten => s,n,Dial(${CH}/${ARG1},60,t) Looking at the execution, I can see what the AVAILCHAN variable returns Executing NoOp("SIP/1001-9906", "AVAILCHAN= SIP/teliax") in new stack However, in order to send a SIP call to Voxee, I have to use the configuration SIP/${EXTEN}@voxee and I can't see how to do that. SIP/teliax/${EXTEN} works with teliax but not voxee. -- Chris Mason NetConcepts (264) 497-5670 Fax: (264) 497-8463 Int: (305) 704-7249 Fax: (815)301-9759 UK 44.207.183.0271 Cell: 264-235-5670 Yahoo IM: netconcepts_anguilla@yahoo.com -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
