Summary:                    Inbound calls are dropped after 15 mins and several
Status 400 and 422 messages in SIP trunk against Huawei SoftX3000
Description: 
Inbound calls (haven't test oubound yet) are dropped after 15 mins (aprox
915 segs) in Asterisk 1.6.2.1 and 1.6.2.0 on a SIP trunk against a Huawei
SoftX300 SoftSwitch.

Several "Status: 422 Session Timer too small" and "Status: 400 Bad Request
- 'Malformed/Missing URL'" are shown before the call is dropped.

I'm attaching a CLI SIP debug with the issue.

This doesn't happen in several Asterisk 1.6.0.x installations.
