Note: If your switch requires the timer option; for instance, Huawei SoftX3000, it needs this optional field and drops the calls with "Session Timer Check Message Failed", then you may be able to revert back the commit that took away the Require: timer option which is an optional field by:
1.3.0.23 is their software version, not the SIP protocol version. Both will be using SIP v2.
Some different devices do have different interpretations of that standard though, which can lead to interop problems between different device types.I suggest you contact your carrier to ask why they're sending 500 - they may be able to advise you what is causing this error.-Steve

_________________________________________________________________________Hi All
Due to time constraints I'm posting here for the hope for a quick response.
I'm currently trying to setup a Trunk to our upstream Carrier.
The issues we are facing is that inbound calls from them are working 100%.
Outbound calls to them are returned with a 500 error.
The only immediate differences we could pickup was the SIP versions.
They have a Huawei MSOFTX3000 running SIP version 1.3.0.23.
I'm running freeSWITCH 1.5.1b+git~20130414T025052Z~969eae39d9
Is there any possibility someone could help me figure out what compatibility issues between the SIP versions could cause, especially for out bound calls to the Carrier?
Thank you very much
Kind Regards
