I'll try to to send a 10-pages long fax and report here my findings.
2 pages are enough to see whether there are any problems.
As far as P2MP signaling is concerned, you can hook up to 8 devices (64 <= TEI < 127) to such a PSTN connection. To simplify installations, there is usually a bus topology, but proper termination can be problem (in rare cases).
I am not familiar with the details and terminology in France, but have a look at little box in http://de.wikipedia.org/wiki/Network_Termination_for_ISDN_Basic_rate_Access. If this looks familiar, you do have an S0 bus.
If you do have an S0 bus and a P2MP connection, then it is somewhat easier to dissect the problem. jg -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
