Hi All,
Spent most of the last two days googling and forum surfing to find an answer to this! Pretty sure I am missing something straight infront of me 
I have setup an Asterisk test rig with 5 SIP phones, 3 from a company called Safecom and 2 from Aastra (a 480i and a 9133i).
The Safecom phones are all working fine, I can ring between them quite happily. With the Aastra phones though I can only make calls from them. If I ring either of the Aastra phones I get no ringing sound on the line and the Aastra phone doesn’t ring. Within the Asterisk console whenever I ring an Aasta phone I don’t get a SIP/xxx is ringing event.
Safecom -> Safecom
- Called 101
- SIP/101 is ringing
- Nobody picked up in 10000ms
Safecom -> Aastra
- Called 103
- Nobody picked up in 10000ms
I have followed some other config posts for the aastra phones on this forumn thinking it may be a phone config issue but to no avail. Any pointers would be most appreciated.
