Voice via Quectel EC25-E WORKED (not VoLTE, because there is no LTE registration) with Asterisk 20.4 !

[CpServiceSpb]

I could build and set up the channel from sources on Asterisk 20.4 (on Ubuntu 22.03 x64) for Quectel EC25-E (2c7c:0125) plugged via mPCIe2USB.
Both sides voice works.
And there are 3 points:

1. modem auto up by IMEI and IMSI don' t work;
   At least at me.
2. As I can not register the modem at 4G network, for unknown reasons for me, I couldn' t test VoLTE;
3. IVR doesn' t work to due to there are not slin voice files at my system at the time.
   But incoming call is in slin codec, it is what I saw at Asterisk console.
   But MOH works.

I will coocked deb package rules for make aserisk_chanquectel.deb
Where is to put it ?

Questions ... youare wellcome.
