I programmed the meet-me conference (I think correctly by the book), from internal extensions it works fine, but when calling from e.g. mobile to access the conference over SIP trunk I cannot join it. I hear the tone but when entering the conference number and the conference PIN the input seems not accepted. The SIP trunk is configured in SIP peer profile to use MBG as SIP proxy, I have enabled the Allow Out Subscriptions for Remote Digit Monitoring (set to Yes) and Request Outbound Proxy to Handle Out Subscriptions (set to Yes) options in SIP Peer profile. I also configured the KPML (username and password) in the SIP peer profile and in MBG.
Any ideas what could be wrong?
