Is there any way to pu the spa 9000 behind the 7975g phone. I have a sllm224 switch and a dlink router. Do I have to have call manager and if so what hardware should I swap. I just started a very small business but plan to grow only have 2 phones atm.
I have read up on the subject, and it appears that we don't support the 7975g in SIP mode without CUCME or CUCM. It is not supported with 3rd party SIP call control even when the 7975g phone is running a SIP load. Currently, the only phones supported in SIP mode with 3rd party call control are the 7940 and 7960 phones.
I am not saying that this won't work, but this might be a very difficult and undocumented process.
The 7900 Series phones do not work with the SPA9000 IP PBX, unless they are in SIP mode. However, there are more affordable models of SPA phones. More information on:
