Unable to complete a call between two SIP Provider

[Ramamoorthy Shanmugam]

Hi All,

SIP trunk was configured between two provider . I am able to make calls to them but they are not able to make calls . There are getting fast busy " SIP/2.0 500 Internal Server Error " with Q.850: cause=127

from CUBE I am getting

SIP/2.0 422 Session Timer too small

from my CUBE end i configured session expire value in globallly .

min-se 360 session-expires 360

for call call manager "1800"

Please let me know what is the issue , need to change any value from my end or remote end .

Thanks & Regards,

S. Ram
