Hello Asterisk Community,
I’m currently facing an issue in configuring a custom dialplan in FreePBX/Asterisk that’s intended to enable simultaneous dialing of two different external numbers by dialing a single extension.
Background and Goal:
My setup consists of FreePBX with Asterisk, and I have a successful track record of making and receiving individual phone calls. However, when trying to configure the system to simultaneously dial two external numbers, I am encountering difficulty. The aim is to dial extension ‘7878’ which should trigger the system to call two different external numbers simultaneously.
Approaches and Methods:
I have tried different methodologies, including creating custom extensions, custom context, leveraging local channels, and even the call file method to stimulate the calls. Despite these attempts, I continually receive a busy signal and no response when trying to use the custom dialplan or dial the created extensions directly. Additionally, we also ventured down the route of setting up a Ring Group, which also unfortunately did not yield a successful result.
Two custom extensions - ‘881’ and ‘882’ - have been created, each one intended to dial a unique external number via specific outbound routes. The dial setting for each extension is in line with its outbound route: ‘Local/908XXXXXXXXX@outbound-allroutes’ for extension 881 and ‘Local/918XXXXXXXXX@outbound-allroutes’ for extension 882, where ‘8XXXXXXXXX’ are the actual external phone numbers.
These extensions are not set up on any softphone or application; they are designed solely to make outbound calls to the specified external numbers as part of the custom dialplan.
A custom Ring Group (‘7878’) has also been set up with these two extensions (881 and 882) included in the Extension List.
Despite implementing these configurations and carrying out multiple dialplan and core reloads, I am unable to achieve my goal. Attempting to dial extension ‘7878’ results in a ‘403 Forbidden’ response, accompanied by a busy signal. Also, attempts to directly dial the custom extensions (‘881’ and ‘882’) have been unsuccessful. To troubleshoot the issue, we’ve checked the Asterisk logs at various log levels, but none of the standard SIP messages such as “SIP INVITE”, “SIP ACK”, “SIP CANCEL”, “SIP BYE”, “SIP REGISTER”, and “SIP NOTIFY” were present. The absence of these messages has made troubleshooting significantly more challenging.
I’ve conducted extensive troubleshooting, even inspecting my NAT settings, network configuration, and ensuring that the firewall is not causing the problem, all to no avail.
I’m seeking your valuable insights and suggestions to address this issue. Any input towards helping me configure a custom dialplan for dialing two numbers simultaneously will be greatly appreciated.
Thank you for your time and consideration.
