Hi all. I'm new in configuring 3CX. In general, most parts are working fine. The only real problem I have is the following: A user uses an Android-Client and calls a number from the regular phonebook which starts with +41 (countrycode for Switzerland, for example). We have to dial 00-41, in US it would be 011-41. Then I'm getting a error, that the target can't be found. On the Activity-Log on the Server I can see these entries: [CM503001]: Call(C:32): Incoming call from Extn:101 to <sip:+firstname.lastname@example.org:5060> [Flow] Target endpoint for +4112345678 can not be built! Call(C:32): from Extn:101 to +4112345678 doesn't match any outbound rule. No outbound rule could be selected. [CM503014]: Call(C:32): No known route from Extn:101 to target: <sip:+email@example.com:5060> [CM503020]: Call(C:32): Normal call termination. Call originator: Extn:101. Reason: Not found The Problem itself is clear: The PBX doesn't know how to handle the + in the OutBound Rules. So I have set up an OutBound Rule as following: Calls to numbers starting with prefix: + Route 1: Provider, Strip Digits: 1, Prepend: 00 This should dial 0041 instead of +41, right? But this doesn't work at all. The + is just ignored in the Rule. How can I handle that? Thank you for your help.
