Description:When negotiating T.38 pass through, T38MaxFaxBitrate is set incorrectly.

Example: cisco GW sends reinvite to asterisk with T.38MaxFaxBitrate to 7200. Asterisk sends OK but with T.38MaxFaxBitrate 9600 and cisco sends BYE (it should be 7200).  See attached patch, but i dont know if i doesnt brake anything. I have tested both direction and this fixes my issues.

Ok, anyone that can check the standards here and see if it's ok to answer with a different setting?

Could you also attach the sip debug? Just curious to see the T38 in the SDP...

Still there? I would really like to see the T38 in the SDP, I'm not convinced this patch is quite right.

Any update?

I'm uncomfortable with changing this without seeing those debug logs, so please reopen when you can get 'em.
