do not know, generally use OBI110 (freq. single side audio, delay response) or Et263 service (time to time error code 404....) ip01 seems stable.
So currently everything is unstable. ....!!!! except ip01 alone.

IP01现在放在香港。 以前是用SPA3102，vigor, IAX..  IP01 不太稳定。起码比OBi110好。
现在OBI110-obitalk-OBi110 Voice Delay, single side audio, OBI110->IP01->OBI110 常常连不上线。（电话不通）。
开始改用OBI110-ET263-OBI110. 是最稳定的方法。

Two year before, I have send several router to increase its internal Flash/RAM, or add additional antenna. (they solder a big ROM/RAM)
May be we can do the same for IP-01, to recover its value.
As shipping cost is expensive now, besides increase the Flash/RAM size, what can be added? Add SD Card slot?

for me, ROI for IP04 is very low. IPXX is not stable, so just use it as backup or testing purpose.
Wish to turbo charge the IP01, so that it will not become garbage.
Any suggestion for IP01 ?  if increase the RAM or NAND Flash to bigger size, does it help to adapt the new switchfin firmware? or add SD card is the only way.
Any diagram for add SD CARD?

i see, that is a big problem. Do not want to hack the firmware.
