An IVR is accessible through FXO or through SIP (I have two different numbers) on the same server. The prompts of the IVR are WAV files.
If I call through PSTN/FXO, the quality is good. But if I call through SIP, the prompts will be terrible quality (only first few seconds of the prompts). It is only after I reboot the server that the quality will be good (even better than FXO).
The problem is that I don’t want to reboot my server every day …
Does anyone has an idea why I need to reboot my server so frequently for the SIP to work well, as the audio prompts are fine through FXO even if the server hasn’t been rebooted for a year.
thank you for any help!
