your suggestion to turn off SIP ALG on provider's router was probably
correct. no problem until now. Thank you very much.

I just found out another issue. I had a pjsue client in that network
which called specific number when turned on. It was working perfectly
with the old provider with working SIP ALG. But now with this provider
and SIP ALG disabled I am not able to make the call using pjsua

My pjsua config looks like this:
--id sip:ext at asterisk.domain
--registrar sip:asterisk.domain
--proxy sip:asterisk.domain
--outbound sip:asterisk.domain
--realm *
--username username
--password password

The pjsua client successfully registers but is unable to call.

I see the following:
IP address change detected for account 1
(localip:5060-->nattedip:newport). Updating registration (using method
Temporary failure in sending Request msg INVITE/cseq=...., will try
next server: Unsupported transport (PJSIP_EUNSUPTRANSPORT)

What could be the problem? How can I convince pjsue to work correctly
behind nat?
