Hello we are testing at the moment the 3CX PBX Software and having problems with the DID routing. At incoming calls from outside we getting the error message: Can not find source by following specs: From: '06641005595'; To: '100'; Rline: '100'; Contact: '06641005595' The caller from outside dials the number 0720 / 101111 - 100. Our main number is 0720 / 101111. As you see in the error message in the "to" field there is just '100' transmitted. Is it a problem with the provider that he's sending just the 100 without the whole number string? We tried to define DID rules like 100, 072010111100, 720101111100 , but still with the same error in the message log. Are there any possible settings for the Gateway in the advanced settings tab or does the provider have to change the incoming string? thanks for all help replies.
