[asterisk-ss7] chan_ss7 - T22 timeout (No 'circuit group reset acknowledge' from peer)

[Low Yu Siang]

I am connecting to a Siemens switch. I waited for hours, T23 timer are also appearing. Currently I see in the chan_ss7 code that the timeout value is set at 30 seconds, are you suggesting that I should modify the code so that it is >120 seconds? 

Thanks.
