Модель телефона в студию.
Рабочий конфиг цискосвитча для работы телефонов 16**/96** (естественно вырезка)
При этом предполагается, что DHCP-server и телефоны находятся в разных VLAN.

!
lldp run
!
vlan 30
name voice ! strictly AVAYA recommended due to phones lldp compatibility
!
vlan 10
name users ! anyname
!
interface vlan 30
ip helper-address 192.168.1.1 !(dhcp-server ip)
!
interface FastEthernet3/48
switchport trunk encapsulation dot1q
switchport trunk native vlan 10
switchport mode trunk
switchport voice vlan 30
spanning-tree portfast
!

Рекомендую на каждый телефон создать резервирование в ДХЦП. Сильно упрощает жизнь.

Насчет сниферов и т.д. - дело в том, что филиал удаленный - я в Москве, они в Омске. Слово Снифер там для них - кличка собаки.

Рабочий конфиг такой: (правда не циска), телефоны AVAYA 9620L\9630
