How to set up VoIP from MGTS via GPON?

Question

Telephony

MGTS OJSC in Moscow connected me to the Internet via optical fiber by installing a PON ZTE 660 router with the following characteristics:

• Model F660
  
• Hardware version V2.3
  
• Software version V2.3.1P1T1S
  
• Bootloader version V1.0.1
  

The Internet works - on the first port, the TV - I don’t remember which one, because it’s not physically connected, and an analog phone via POTS1. I want to abandon the analog phone in favor of VoIP, and hang it on one of the free Asterisk ports. Buying a POTS ⇒ VoIP gateway is nonsense, since the router has a VoIP ⇒ POTS gateway.
To begin with, I want to test it on a software SIP client - MicroSIP. Everything rested on his settings, because the respected support of MGTS OJSC, to the best of their competence, politely sends to hell ...Google gives conflicting answers. For example, I found different servers, sbc.sip.spdop.ru:5060 and msk.ims.mgts.ru, different login format. With a password, it’s generally not clear where and how to look for it: nothing is said in the router settings about VoIP settings, nor a password, even hidden asterisks. Only the status of POTS lines.
If anyone has experienced this, please help!

Answer 1

If there is no mention of a VoIP connection in the web interface, then it is likely that it was simply hidden from the user's eyes. The settings for telephony are still in the configs.
Judging by this article on Habré , this router has access via telnet (root:root). I think there, walking through the file system, you can easily find all the logins, passwords and host addresses for ip-telephony.

In my case, telnet access turned out to be root: Zte521

Entered data into the program, writes that the server was not found. Yes, and msk.ims.mgts.ru does not respond ((

I'm on f670, deleted all WAN interfaces, created a new one with INTERNET + VOIP set.
Built-in client started.
After a reboot, another INTERNET interface is created and nothing works until it is removed.
Then everything works again.
