I’ve 1 asterisk server with 2 SIP trunks connecting to 2 different sites.
i.e, SiteA PSTN>SIP GW1>Asterisk>GW2>SiteB PSTN
I’m trying to establishing a toll free connection between SiteA and SiteB. When i try to place a call from SiteA to SiteB, it seems that Asterisk is connecting properly (between GW1,Asterisk & Asterisk,GW2). I get a 183 Session progress message and i can hear a ring tone but the phone at SiteB does not ring or connect. Can anyone advise me what else i should check?
Is this a valid setup? Any advice is greatly appreciated.
