I am trying my best not to be completely annoyed at the "somewhat limiting" remark after going over the countless hours I spent making sure this feature work and then being patient with 2 people insisting there was a bug when they both shared an identical misconfiguration.
"somewhat limiting" was because my experiments up to now with Polycom and SIP/TLS were successfull with domain names only. However, I am going to inverstigate this further to see how this can work with IP only.
In the meantime I've documented the required configuration under the Polycom wiki page.
If we started doing DNS lookups everywhere so hostname could be interchanged with IP we would have large blocking all over the place when the DNS was not available and horribly messy code doing all the lookups. There was already an experiment called project asterisk that proved the flaws in this design approach.
I think that's why some of us move from Asterisk to FreeSwitch. I also preffer less to no DNS lookups on a critical system which must work even when there are some kinds of communication problems.
