SIP headers in Source Numbers

[CyMac6poD]

Good day
first of all - my situation:
AVAYA IPO R7.0(12) and SIP trunk.
The problem is - outgoing call works perfectly well, but incoming calls disconnects. call come to my PBX, but in the moment of answer providers side give me BYE with Reason: SIP;text="SSF00159L00761 Session Timer Check Message Failed". i think this happens because provider Required:timer, but my IPO only Supported:timer.
My question is - is there some source numbers command to operate SIP Headers and replace Supported:timer to Required:timer

Huawei SoftX3000. - End of Life by the looks....

perhaps there will never be proper interoperability between the IPO and the Huawei SoftX3000?

Maybe you are right. but that's not the point. Try to change version IPO to 6.1.20. No results for now. To be continued....
