Sip phone

[3Sixty]

I have a Mitel 3300 running version 7 sp1. The issue I am experencing is with a sip handset. I have the handset registered and the connection is established. The problem is as follows:-

I can originate a call from the SIP device and everything works as follows.
No issues with calls to external party
No issues with calls to other Mitel handsets
No Issues with calls to other analogue devices

The only issue is when any device rings the SIP unit.

If I ring from a Mitel handset internally. Call set up is established and the handset rings but no speech path in either direction from SIP or any other handset Analogue, Mitel or external.
Sip to Sip same issue occurs but not sure if this is related to the unit.

I have looked at the system and I am waiting on a small hub to run some wire shark traces but my initial diagnostics is the SIP handset.

Sip Handset is Interquartz I10

Any advice or pointers would be greatly appreciated

Thanks

at a guess i would say perhaps its a codec issue or routing issue

are minet phones and sip handset living in the same network as the pabx?
have you restricted any codecs on the handset
have you set a sip device capability for the handset

If I never did anything I'd never done before , I'd never do anything.....

Sorry should have provided the information

The phones are all on the local subnet within the same IP address. I have tried restricting the Sip unit to only using G711 and G729. This has not changed the results the same issue still occurs calls originated from SIP device work perfectly to Mitel external lines and sip lines. Calls made to the Sip device from any of the previous Mitel External Sip Trunks result in no speech path..

If I never did anything I'd never done before , I'd never do anything.....
