We are having a setup as mentioned below.
Phone --- CUCM -- QSIG ICT GK --- GW ---- H323 PRI GW --- Phone
Like this, multiple CUCM clusters are pointing the QSIG ICT towards GK.
With this scenario calls are not going through from a phone in CUCM towards phone in other side and as we know, this is because Annex M1 not yet implemented in H323 or in any other protocol, Due to this we are creating another topology as mentioned below.
Phone --- CUCM -- Non QSIG ICT GK --- GW ---- H323 PRI GW --- Phone
Due to this case the number of trunks to GK has become almost doubled, 1 for QSIG and another for Non QSIG. we don't want to over load the GK as well
Just wondering is there any possibility for GK.
1) To route only QSIG calls between clusters and not to Gateways
2) And by removing the QSIG feature send the call to GW so there is no need of additional Non QSIG trunk to GK from the CUCM clusters.
