[Users] Re: Avpops: avp_op() function

[Daniel-Constantin Mierla]

Hello,

the appropriate mailing list for openser is user at openser.org

The CSeq number is part of the header and is stored in AVP as a string. 
You have to make a cast to integer/number and then perform the 
operation. See avp_copy() for cast. The avp_op() operates only on avps 
with integer value.

Cheers,
Daniel
