I have a customer that has recently upgraded their network and now their Aastra 9133i phones are loosing their connection to the Asterisk server. They were using an external Asterisk server and now we have installed a new internal server with Asterisk 1.4.8 on a SIP/IAX implementation with no Zap cards. Only hard phones seem to be having problems keeping a connection to the server, soft phones do not seem to be affected. I was wondering if anyone here has had an experience where hard phones have problems connecting to the server. The client has good Cisco intelligent switches on their network. Is it possible that they maybe sending some QoS or VLAN information that confuses the phones? -- Telecomunicaciones Abiertas de M?xico S.A. de C.V.

At the end of the day they have poor support, as in "Maybe we'll fix it in a subsequent release"
