Hi,
I have an Asterisk PBX 1.2.18 connected to a remote Snom 360 (firmware
ver: 6.5.10), outside my LAN. If I call the Snom, I sometimes cannot
hear the called party and the called party cannot hear me. When this
happens, I get the following message from Asterisk CLI:

NOTICE[19164]: chan_sip.c:2012 auto_congest: Auto-congesting
SIP/3-081da588 -- SIP/3-081da588 is circuit-busy

I searched on internet but found nothing (something similar was an old
bug but now fixed).

Is there anybody who knows what is causing this strange (random) behaviour?

Consider that:
- there is no firewall between Asterisk and the Snom (Asterisk <->
router A <-> internet <-> router B <-> Snom 360)
- I have a Grandstream ATA connected to the same router where the Snom
is connected but the ATA works good.
- I tried to change cables without success
- rtp debug shows no voice packet is sent between Asterisk and Snom

Any help is appreciated.

Thank you.
