SIP Max-forwards

Voice & Telephony

Hi ,

I need your help.
I need to do a TRoute inside a strategy to send the call to an external destination. The problem is that the destination is several sip hops away and I get a “SIP/2.0 483 Too Many Hops” error message.

The root cause is that when issuing the TRoute , the SIP Server is sending an INVITE message with a Max-forwards value of 9.

I’ve search the docs and there is no option to send this. There is only the oos-options-max-forwards option which sets the Max-forwards value, but just for the SIP OPTIONS messages.

Any ideeas on how to incres the value of max-forwards?

Thank you,
DB

Solution:

You can add a Section in SIP Server named like the sip message you want to modify containing the parameters you want to add or edit:

INVITE/Max-Forwards=70

Now SIP INVITE messages sent from SIP Server have the parameter Max-Forwards:70
