Snom320
Version
This phone call call the page group, can dial *90ext for intercom, can call a Snom300 directly, can call a Snom370 directly
Now add a third phone to the group (Snom370 or a Snom821)
These phones can't call themselves to check VM, they can make the 320 and 300 ring but when you answer the phone the person on the 370 or 821 can't be heard. However, if the 300 or 320 call the 370 or 821 it works just fine.
For whatever reason it appears that the issue is with using the 370 and/or 821 and that the outbound data is not being sent from these phones.
Back and forth between the 300 and 320 is fine. From the 300 and 320 to the 370/821 fine. From the 370/821 to anything else not so fine.
BTW- Do you know of anyone that could help double check our system and make sure we have this setup properly?
