Issues with Biktorgj Custom Modem Firmware

[JadenSki]

So I recently decided to install Biktorgj's Custom Modem Firmware on my ppp, as it said in the documentation, there is no reason not to, and only added benefit. I installed it using this guide. After the installation, everything seemed to work fine (eg. sms, calls...). I then tried to communicate with the modem using sms as is described here. My messages didn't send, however, and I never received any responses. I also discovered a weird bug where my audio and mic will completely stop working for calls. I cannot hear or be heard by the other phone. Also when I check my voicemail, I hear no audio either. I don't know for sure if the firmware is causing the issue or not, but, it didn't happen until after the installation. Rebooting does not seem to do anything, however, it will randomly start working again before it quits once again. Any insight or advice on these issues will be greatly appreciated. I am currently running the latest stable version of Mobian with Posh. Thanks in advance!
