Hi, I interconnected 2 Elastix boxes using DUNDi, dialing extensions from each box works fine, but when I try to dial our using a trunk in the other box, I always get an error. Configuration: Box A: 4 Zap trunks with outbound route 1 containing dialing rule #53|NXXXXXX All local extensions can dial out with no problems including when dialing #53XXXXXXX. Extensions_custom.conf modified as follows: [dundi-priv-via-pstn] include => outbound-allroutes Box B: 1 SIP trunk with dialing rule NXXXXXX. All extensions can dial out with no problems. When dialing #53XXXXXX from any extension connected to box B, I get an error message. Any suggestions???? Thank you in advance for your help!!!!!
