Has anyone tried setting up a Cisco 7911G to work with SIP Zadarma?

Question

SIP

The second day I struggle with this piece of iron and I can’t set it up to register with Zadarma in any way ... I tried different firmware, now 8.5.4 ... On the 9th branch, he did not even send registration requests. According to the log, it sends SIP registration requests
