Hi all,
I’ve seen a few open topics with similar titles but none that really seem to get to why this is happening. I have this issue where, when calling outbound from my PBX to some certain friends cellphones, they stop being able to hear me usually exactly at 10 minutes into the call. I can hear them, they just can’t hear me.
A couple other things I’ve noticed while playing around with this issue for several weeks:
- This only happens when the friend’s cellphone is on LTE/5G. If they are wifi calling there is no problem
- This doesn’t happen for everyone. I’ve been on support calls for over an hour with no issue, only a few friends with their cellphones
- I can create this issue immediately by calling using a softphone and switching from wifi to LTE during the call on the softphone device, same results as above where my audio stops going
A preliminary look through very verbose logs doesn’t seem to indicate any issue, but I’m a bit of a noob so there could be something I’m missing. Any help would be appreciated. I can provide logs if needed.
