I've setup the following in extensions.con:
exten => 2200,1,Ringing
exten => 2200,2,Wait(2)
exten => 2200,3,Answer
exten => 2200,4,Zapateller
exten => 2200,5,Macro(stdexten,2205,SIP/2205)
This works as expected if I dial from a SIP phone on my desk. However, if I dial in from the PSTN (through a SIP provider) it fails while trying to play ths SIT with:
Apr 8 18:53:12 WARNING[1209269552]: rtp.c:407 ast_rtp_read: RTP Read error: Resource temporarily unavailable
Any idea what's going on? My suspicion is that the PSTN gateway hasn't setup an audio path yet, although I thought Answer would do that.
Cheers,
Brian
