Hello,
A strange problem while I ring MGCP channel on an ADIT 600: it rings OK, but when the call is replied, a second FXS line is connected to the channel. The dial tone from the second line is heard over the channel; after a time-out there is fast busy, and no any tone at the end, but the second line stays connected till the call is closed.
The line in the log below " MGCP mgcp_new(MGCP/aaln12@10.69…" tells that FXS line 12 has been connected to the channel, and the line shows amber ligt on the ADIT, so it is open. There is no reason for line 12 to open - I dial line 1 (aaln/1), as shown.
Some one with an idea what is happening? Why line 12? I did change two computers, did reinstall asterisk few times, and it persists.
Configuration: Stock asterisk Asterisk 1.8.8.2~dfsg-1 from Debian Wheezy on HP DL380 G3; also same asterisk version on Neoware E140 with Debian squeeze, same situation.
Dialplan:
// Trunk entry from voipms-01
context TRUNK-IN {
5143168452 => { Answer(); Dial(MGCP/aaln/1@10.69.240.16); Hangup(); }
