With CCM 3.3(2)SPC we had several users using IP
Phones (7960/40) at there home offices connected via
Cisco VPN devices quite successfully using SCCP.
However, now that we have upgraded to CCM3.3(3)SR1
the functionality of these VPN based IP Phones has
diminished. The same configurations are present on
our PIXs and VPN concentrator.
--Successes--
VPN IP Phone can call an external number with two
way audio.
VPN IP Phone can host a meetme conference using a
public DN and both external and internal callers can
participate.
VPN IP Phone can receive a call and forward it based
on forwarding rules (like CFAll, CFNA to voicemail,
etc).
--Failure--
VPN IP Phone will ring when an internal or external
call is received (Caller ID is fine), but the VPN
recipient is unable to retrieve - answer the call.
Attempts to pick up the handset, press headset or
the speaker button do not answer the call; though
the headset and speaker button do light up. If a
answer attempt is made - any call forwarding rules
like no answer to voicemail do not work.
Are the 3.3(3)SR1 Phone loads solid? Are there now
additional concerns for VPN based SCCP phones in this
release?
---Thanks---
