Flowroute as SIP provider.
My client is having issues with leaving voicemail on external phone numbers getting clipped around the 10s point. I was curious if there is something I am missing to remedy this.
In Asterisk SIP Settings, try setting RTP Timeout to 180 (3 minutes). If no luck, paste a log of a failing call, including SIP trace, at pastbin.freepbx.org and post the link here.
I set the RTP Timeout to 180.
RTP Hold Timeout is 300 and RTP Keep Alive is set to 0.
Sound about right?
Check and see if AMD, Answering Machine Detection is enabled. If so, try disabling it. It is a module. My nephew had a similar problem when leaving messages on his FPBX and this fixed his issue.
Just disabled AMD.
Will monitor to see how that works for the next week.
Just curious if this might have fixed your issue.
