I have just upgrade asterisk 1.2 to 1.8 and we have numbers starting from _71XX. now what happen if i dial any 711X number my polycom just dial 711 and say busy number look like my phone doing some regex itself. like 911 number..
Did you get what i am trying to say ? it was working before with 1.2 but after upgrade 1.8 it started issue. why its just going with 711* 611* 511* etc…
