12345678099 doesn't match _1234567800. The problem is the other side is setting the R-URI to sip:123456780000@provider for any number, so the EXTEN matched in the dialplan is 123456780000. Ask them to fix this problem. > I wonder, if I really need to grab the extension with > Set(DN=${SIP_HEADER(TO):5}) or something similar? Yes, something like if they can't fix the R-URI: exten => X_.,n,Set(TO=${CUT(SIP_HEADER(To),@,1)}) exten => X_.,n,Set(TO=${CUT(TO,:,2)}) exten => X_.,n,Goto(somewhereelsetopreventloops${TO},1) > Another issue is, that I don't like asterisk to decline foreign INVITE > requests.

Don't enable guest access, or send any unknown/guest to a context that will just hangup. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
