Considering that you made progress on your initial problem by setting "nat=force_rport" (resulting in connected calls with no audio) and now you're mentioning the use of "externaddr", I'd recommend a very careful reading of the "NAT SUPPORT" section of sip.conf.sample in the configs directory of the Asterisk source tree.

I did read all those documentation, belive me. Also keep in mind that I *ONLY* face this problem with this provider, people using voipbuster or sipdiscount should have the same problem.

Concerning externaddr, this test server -dedicated to asterisk- being running in VM since ages, I never would suspect a NAT issue! Especially if previous 1.4 and 1.6 version are running smoothly ...

In Asterisk 1.8, there is a new configuration option named "media_address" which may be of particular interest.

media_address seems not an option, can be set only in general not per peer.

This is confusing because your first email said you had "nat=no" in your working 1.6.24 setup, but everything you're saying indicates a NAT problem to me.

Again, 1.6 version is perfectly working with this setup and conf files, and before 1.4 was too. And those both asterisk versions with *this* provider.

. A diagram showing all network elements between your Asterisk server and the remote host would be helpful.

Phone registration:

phone (Snom320 and GS GXV3175) -> firewall1 (linux router) -> Internet -> firewall2 (linux router) -> VM -> phone account

Call:

phone account -> Out of VM -> firewall2 (linux router) -> Internet -> Peer IP -> ???

To avoid further confusion, please include full and unaltered logs, SIP traces, and configurations in future posts.

During the time you and Andres replied to my post ;-) I got the same idea then him; and guess what, it's working! So problem is Asterisk 1.8/10 in VM _only_ this provider(s) which are all Dellmont services.

Can someone confirm the problem?

Question is now, who is faulty? Should I open a bug?

Thanks for your time and support.
